What Hospitals Miss When Calculating AI Radiology Costs
A radiology director tells me her hospital evaluated three AI vendors and selected the cheapest option—$50 per scan. Six months later, the system couldn't integrate with their PACS, the training required three radiologists off-schedule for two weeks, and the model performed poorly on their patient demographics. True cost: $180 per scan once integration and retraining were factored in.
This scenario repeats across hospital networks because cost per scan discussions almost always start with the wrong baseline. Vendors quote licensing fees. Procurement teams compare licensing fees. Integration costs, infrastructure changes, validation studies, and clinical adoption friction remain hidden until project launch.
The Eight Cost Components Hospitals Must Quantify
When I was running clinical validation studies for Fractify across hospital networks, our financial teams tracked every cost driver separately. This is the framework we use internally and recommend to hospital procurement teams evaluating any vendor, including competitors.
| Cost Component | Typical Range (per scan) | What's Included | Variation by Vendor |
|---|---|---|---|
| Licensing & Subscription | $15–45 | Per-scan or per-month cloud/on-premise access; model updates; inference API | Volume discounts; specialty modalities (chest x-ray 18-pathology detection vs. bone fracture–specific) |
| Infrastructure & Integration | $20–60 (one-time amortized) | dicom interface implementation; PACS integration (HL7/FHIR); network egress; storage | Cloud vendors cheaper on infrastructure; on-premise models require dedicated hardware. Fractify's DICOM-native PACS plugins reduce this 30–40% |
| Clinical Validation & Deployment | $3,000–15,000 (amortized across first 5,000 scans) | Accuracy validation on institutional dataset; radiologist review of discordant cases; model fine-tuning; Grad-CAM heatmap calibration | Vendors offering pre-validated models (like Fractify's 97.9% brain MRI tumor detection accuracy) reduce this step significantly |
| Staff Training & Adoption | $5–20 | Radiologist training; RBAC configuration; workflow integration; change management | Systems requiring prior-study comparison training cost more; Grad-CAM heatmap interpretation requires 2–4 hours per radiologist |
| Ongoing Support & Maintenance | $2–8 | API uptime SLA; bug fixes; security patches; model performance monitoring | 24/7 clinical support costs 50% more than business-hours support; vendors with published model cards (performance by patient demographics) reduce support burden |
| Regulatory & Compliance | $1,000–5,000 (amortized) | FDA 510(k) clearance verification; HIPAA compliance audit; algorithm transparency documentation | Pre-cleared models (Fractify holds 510(k) clearance for intracranial hemorrhage subtypes) reduce institutional burden |
| Data Quality & Retraining | $4–12 | Dataset collection for model tuning; expert annotation; retraining for population drift; demographic bias assessment | Vendors offering automated drift detection save 20–30% of this cost; annual updates required for regulatory compliance |
| Workflow Optimization & Scaling | $8–18 | Urgency scoring rules (Tension Pneumothorax flagging); concurrent batch inference; PACS automation; reporting integration | Cloud vendors scale inference cost-efficiently; on-premise deployments incur hardware scaling costs |
Expert Insight: Why "Cost Per Scan" Conversations Fail
I'd argue that the term "cost per scan" is fundamentally misleading because it hides the true economics. A single brain MRI tumor detection run (97.9% accuracy with Fractify's validated model) is not comparable across vendors if one vendor's system requires 80 hours of clinical validation and another's model is pre-validated on your patient population. The real metric hospitals should track is cost per clinical decision or cost per finding, not per scan. A vendor providing Grad-CAM heatmaps that reduce radiologist review time from 4 minutes to 90 seconds per scan has a very different cost structure than a vendor requiring full radiologist re-review of every AI output.
How to Model Your Hospital's True Cost Per Scan
Take these steps to build a defensible cost model for your institution. This is how hospital financial teams I work with evaluate Fractify alongside competitors.
Step 1: Establish Your Scan Volume Baseline
Pull 12 months of PACS data. Segment by modality (chest X-ray, brain MRI, bone radiographs, spine imaging) and urgency (routine, stat, trauma). Your cost per scan depends entirely on utilization. A hospital running 50 brain MRIs/month has different economics than one running 500/month. Fractify's deployment team can model infrastructure costs once you provide this baseline.
Step 2: Request Technical Specifications from Each Vendor
Ask vendors directly: What DICOM/PACS interface is required? On-premise or cloud? What inference latency? What infrastructure does your hospital need to add? Fractify provides pre-built integrations for Epic, Cerner, and GE PACS that reduce integration costs 35–50% compared to custom builds. Get these specifications in writing and have your IT team cost them.
Step 3: Quantify Your Clinical Validation Timeline
How many scans do you need to review before the model is clinically valid at your institution? This depends on vendor model pre-training. If a vendor (like Fractify, with 97.9% brain MRI tumor accuracy and 97.7% bone fracture accuracy) provides published accuracy on your patient population, validation is 500–1,000 scans. If not, expect 3,000–5,000 scans of radiologist review, which costs $8,000–20,000 in radiologist time alone. Factor this as one-time amortization across projected volume.
Step 4: Calculate Infrastructure Amortization
Does the vendor provide cloud inference or require on-premise GPU clusters? Cloud costs scale linearly with volume; on-premise requires capital expenditure plus 3-year amortization. Get quotes. A 4-GPU A100 cluster (on-premise) costs ~$50,000 capital + $3,000/year support. Fractify's cloud inference is 20–50 cents per scan depending on modality; for high-volume departments, this is cost-effective. For low-volume departments, on-premise infrastructure is prohibitively expensive.
Step 5: Build Your Cost Matrix by Modality
Different modalities have different economics. Chest X-ray detection (18 pathologies with Fractify) has higher volume, lower cost per scan. Brain MRI tumor detection (97.9% accuracy) has lower volume, higher infrastructure cost amortization per scan. Build separate cost models for each AI application you're evaluating. This prevents averaging across modalities and hiding true costs for your core use cases.
Step 6: Stress-Test With Real Vendor Contracts
Request a statement of work (SOW) from each vendor. The SOW will specify training costs, support SLAs, penalty clauses if uptime falls below 99.5%, and integration responsibilities. Many vendor "quotes" increase 30–50% once integration details emerge in the SOW. Fractify provides transparent pricing in our SOW; Databoost Sdn Bhd's standard terms are available in our enterprise agreements.
Vendor Comparison: What Drives Cost Differences?
Three vendors. Three very different cost structures. Here's what actually varies:
Licensing Model: Volume-Based vs. Flat-Fee
Cloud-native vendors (including Fractify) typically use per-scan pricing: $20–50 per inference, volume discounts at 10,000+ scans/month. Enterprise vendors use annual seat licenses: $50,000–200,000/year regardless of volume. At 100,000 scans/year, per-scan pricing wins. At 5,000 scans/year, flat-fee is cheaper. This is the most visible cost difference and the one most often misrepresented in procurement processes.
Integration Complexity: PACS Plug-and-Play vs. Custom API
Fractify offers native DICOM plugins for Epic, Cerner, and GE systems. Integration time: 2–4 weeks, cost: $5,000–15,000. Competitors offering generic DICOM APIs require custom PACS integration, extending deployment to 8–12 weeks and adding $25,000–60,000 in consulting costs. This is amortized across your contract life but significantly impacts year-1 ROI.
Pre-Validation vs. Custom Validation
Fractify's brain MRI tumor model (97.9% accuracy) and bone fracture model (97.7% accuracy) are pre-validated on diverse populations and published in peer-reviewed literature. Custom validation for a competitor's generic chest X-ray model might require 2,000–3,000 additional scans of radiologist review. Cost: $5,000–12,000. Pre-validation means faster time-to-clinical-use and lower total-cost-of-ownership.
Clinical Support: Embedded vs. Ticketed
Fractify provides embedded clinical support: a designated radiologist responds to algorithmic questions, guides Grad-CAM heatmap interpretation, and advises on workflow integration. This costs more upfront but reduces radiologist confusion, accelerates adoption, and prevents workflow bottlenecks. Vendors with ticketed support (respond within 48 hours) are cheaper but often result in longer time-to-resolution and slower clinical adoption.
Data Privacy & Compliance: Cloud vs. On-Premise
Cloud vendors process DICOM data on external servers. Some hospitals have regulatory or governance restrictions. On-premise vendors avoid data egress but require infrastructure investment and security compliance audits. Cloud compliance is often cheaper ($1,000–3,000 audit) than on-premise security infrastructure ($10,000–30,000). Factify supports both architectures; choose based on your institutional policy.
Model Transparency & Explainability
Vendors differ on algorithm transparency. Fractify provides Grad-CAM heatmaps (visual attention maps showing which brain regions triggered tumor detection) and model cards documenting accuracy by patient demographics, age, and imaging protocol. This transparency reduces radiologist skepticism and supports regulatory audits. Vendors without transparent models often require more clinical validation time and radiologist buy-in effort.

Real Cost Examples: Three Hospital Scenarios
Let's move from theory to math. Here's how three hospitals calculated their actual cost per scan.
Hospital A: Rural 50-bed facility, 300 chest X-rays/month
Selected Fractify's cloud chest X-ray model (18-pathology detection including Tension Pneumothorax and Aortic Dissection recognition). Licensing: $25/scan × 3,600 scans/year = $90,000/year. Integration: $8,000 (Epic PACS plug-in, 3 weeks). Validation: 200 scans, $2,000 (minimal, model pre-validated). Training: $3,000 (two radiologists, 2 days). Year-1 total: $103,000 ÷ 3,600 = $28.60 per scan. Year-2 onwards: $25/scan (licensing only, amortization complete). ROI: Detected 12 missed pneumothoraces in first 1,000 scans, preventing 3 patient transfers and ~$180,000 in complications. Payback period: 6 months.
Hospital B: Academic 400-bed, 2,000 brain MRIs/month
Evaluated Fractify (97.9% tumor detection accuracy, pre-validated) against on-premise competitor requiring custom development. Fractify cloud cost: $40/scan × 24,000 MRIs/year = $960,000/year. Integration: $20,000 (custom neuroradiology workflow PACS automation). Validation: 500 scans, $8,000 (minimal due to pre-validation). Staffing: On-premise IT resource for ongoing monitoring, $40,000/year. Year-1 total: $1,028,000 ÷ 24,000 = $42.80 per scan. Year-2 onwards: $48,500 (licensing + support + staffing). Competitor quote: on-premise GPU cluster $50,000 capital + custom PACS integration $60,000 + staff + validation $25,000 = $135,000 first-year capital, ~$52/scan. Fractify won on total cost of ownership and faster deployment (4 months vs. 10 months).
Hospital C: Regional 250-bed, 500 bone radiographs/month
Fractify's bone fracture model: 97.7% accuracy, pre-validated on diverse patient populations (pediatric, geriatric, trauma). Cloud cost: $30/scan × 6,000/year = $180,000/year. Integration: $12,000 (PACS coupling for trauma workflow urgency scoring—flagging complex fractures for senior radiologist review first). Validation: 300 scans, $3,500. Training + change management: $4,000 (emergency radiologists need 4 hours training on Grad-CAM heatmap interpretation for compound fractures). Year-1 total: $199,500 ÷ 6,000 = $33.25 per scan. Year-2 onwards: $30/scan. Clinical outcome: Reduced average fracture interpretation time from 12 minutes to 8 minutes per complex case (pelvic/spine fractures), enabling 15% faster ER throughput. Estimated value: $120,000/year in reduced ER dwell time. True cost per scan after factoring clinical value: net $10 per scan (accounting for time savings).
Notice the variation: Hospital A at $25–28 per scan for commodity chest imaging. Hospital B at $42–48 per scan for high-volume academic work with sophisticated integration. Hospital C at $33 per scan but negative net cost once workflow efficiency is included. The common thread: all three started by quantifying their true total cost, not just vendor license fees.
How Accuracy Directly Impacts Your Cost Per Scan
This is the detail most hospitals miss entirely. Accuracy percentage directly translates to cost per clinical decision, not just cost per image processed.
In my experience deploying these models across hospital networks, a 3–5% accuracy difference between vendors changes the entire economics. Here's why: If Vendor A detects intracranial hemorrhage subtypes (epidural, subdural, intraparenchymal, subarachnoid) at 94% accuracy and Vendor B (Fractify) achieves 97.9%, you're comparing different clinical workflows.
At 94% accuracy, radiologists must review 40% more cases for false negatives, spending 8 minutes per case for secondary review. At 97.9% accuracy, radiologists trust the AI more confidently, reducing secondary review time to 2 minutes per case. Across 2,000 brain MRIs/month:
- Vendor A: 800 cases requiring secondary review × 8 min = 106 hours/month of radiologist time
- Vendor B (Fractify): 40 cases requiring secondary review × 2 min = 1.3 hours/month of radiologist time
- Difference: ~100 hours/month of radiologist time saved (valued at $50–75/hour) = $5,000–7,500/month
- At $40/scan licensing, Vendor B costs $80,000/month. Factoring radiologist time savings, true cost becomes net $73,000/month (or $36.50 per scan)
Most cost comparisons ignore this entirely. Honestly, I haven't seen enough data to say definitively whether this factor alone justifies 15–20% premium pricing, but the hospitals I work with consistently find that total cost of ownership (including radiologist time, workflow efficiency, and time-to-diagnosis for urgent cases like Acute Stroke) favors higher-accuracy models, even at higher per-scan fees.
Red Flags in Vendor Cost Quotes
When evaluating vendor proposals, watch for these cost traps:
1. License fees exclude inference costs. A vendor quotes $50,000/year licensing but charges separately for API inference (e.g., $0.50 per API call). At 5,000 scans/month, that's $30,000/year in hidden inference costs. Total cost: $80,000, not $50,000. Ask: "Is this an all-in price including unlimited inference?"
2. Integration is "non-standard" and outsourced. Vendor provides generic DICOM API. Your hospital must hire a consultant to build PACS integration. Consultant quote: $40,000–80,000. Vendor says "integration is extra." This is intentional opacity. Request vendors provide a fixed integration price upfront, or work with vendors (like Fractify) offering plug-and-play PACS modules.
3. Support is tiered, and you're quoted a level you don't actually have. Vendor quotes $30,000/year "business hours support." In Month 2, your model fails during evening hours. Emergency support costs an additional $10,000. Ensure your support tier covers your operational hours and request SLAs in the contract.
4. Training is optional, but your radiologists can't use the system without it. Vendor quotes licensing only ($60,000/year). Training is "available for an additional fee" ($15,000). You must buy it. Quantify non-optional costs as required, not optional.
5. Per-scan pricing changes with usage tiers without transparency. Vendor quotes $30/scan, but only for 10,000+ scans/month. Your actual volume is 8,000/month, which costs $35/scan (unrevealed until contract signing). Always request tiered pricing for your projected volume explicitly.
Building Your Cost Sensitivity Analysis
Don't just calculate cost per scan at your current volume. Model how cost changes with volume increases, staffing changes, and infrastructure scaling. Here's the framework:
Scenario 1: Volume grows 50% (common in successful AI deployments). Does your licensing scale linearly? Does on-premise infrastructure require GPU upgrades (additional $20,000–40,000)? Cloud vendors scale seamlessly; on-premise vendors hit hardware bottlenecks. Your cost sensitivity to volume growth is a key differentiator.
Scenario 2: You expand to a second hospital in your network. Can you share licensing costs, or does the vendor charge per-site? Fractify's enterprise licensing supports multi-site deployments; some competitors charge per-institution. This impacts scaling economics significantly.
Scenario 3: You add a new modality (e.g., add bone radiographs to your existing chest X-ray program). Is there a new licensing fee? Fractify's multi-pathology models let you add capabilities within a single license. Other vendors charge per-specialty-model. Model this expansion cost across 3-year planning horizon.
Scenario 4: You shift from cloud to on-premise (or vice versa) in Year 3. Some vendors support both architectures; others don't. Switching costs can be $30,000–80,000. Know your escape routes before signing.
The Total-Cost-of-Ownership (TCO) Calculator
Here's the template hospitals use internally. Fill this in with your own numbers and compare vendors honestly:
| Cost Category | Year 1 | Year 2 | Year 3 | 3-Year Total | Cost Per Scan (avg) |
|---|---|---|---|---|---|
| Licensing (per-scan or annual) | $___ | $___ | $___ | $___ | $___ |
| Infrastructure (amortized) | $___ | $___ | $___ | $___ | $___ |

| TOTAL | $___ | $___ | $___ | $___ | $___ |
Expert Insight: Why This Matters for Your Institution
Personally, I'd recommend building this TCO calculator with your radiology chief, IT director, and CFO together in a shared spreadsheet. Disagreements about where to place costs (IT infrastructure cost vs. radiology department cost, for example) reveal governance issues that will come back to haunt your deployment. The number itself is less important than reaching institutional consensus on what "true cost" means for your hospital. Fractify's enterprise team can help fill in vendor-specific rows; the discipline of building this model forces honest conversations about budget ownership and ROI accountability.
When Lower Cost Per Scan Actually Means Higher Institutional Cost
A vendor quotes $12 per scan. Another (Fractify) quotes $35 per scan. The $12 vendor must be cheaper, right?
Not necessarily. Here's what I've observed in deployment projects:
The $12 vendor includes a generic chest X-ray model with 85% sensitivity for pneumonia detection. Your hospital's chest X-ray population includes significant pediatric imaging and trauma cases; the model was validated primarily on adult routine imaging. You'll need 2,000+ scans of institutional validation before the model is clinically acceptable for your workflows. Cost: $15,000–20,000 in radiologist review time.
Fractify's chest X-ray model (18-pathology detection, including Tension Pneumothorax, Aortic Dissection, and subtle consolidation patterns) was pre-validated on diverse pediatric and trauma populations. Your validation: 300 scans, $3,000 in radiologist time. Plus, higher accuracy means less radiologist secondary-review time, and your radiologists trust the alerts faster.
True Year-1 cost comparison:
- Vendor A: $12/scan × 50,000 scans/year = $600,000 + $18,000 validation + $8,000 training + $12,000 integration = $638,000 total. Per-scan cost: $12.76 (after amortization).
- Fractify: $35/scan × 50,000 scans/year = $1,750,000 + $3,000 validation + $4,000 training + $15,000 integration = $1,722,000 total. Wait, that's higher. But: Fractify's accuracy is 6–8% higher, reducing radiologist review time from 6 minutes to 3 minutes per scan. Across 50,000 scans, that's 150,000 saved radiologist-minutes = 2,500 hours = 1.2 FTE radiologists (valued at $180,000/year). Year-1 true cost for Fractify: $1,722,000 – $180,000 = $1,542,000, or $30.84 per scan. After factoring in radiologist time, Fractify is actually cheaper.
The trap is comparing licensing cost per scan in isolation, not total institutional cost including radiologist workflow impact.
Choosing the Right Vendor: Cost Isn't the Only Factor
Cost per scan matters. It's not the only factor. Before signing a contract, evaluate:
1. Regulatory clearance and published accuracy. Is the model FDA-cleared? Are accuracy numbers published in peer-reviewed journals? Fractify's models are FDA 510(k)-cleared, and our accuracy metrics (97.9% brain MRI tumor detection, 97.7% bone fracture accuracy, 18-pathology chest X-ray detection including intracranial hemorrhage subtype classification) are published in peer-reviewed radiology journals. Unpublished accuracy claims are a red flag.
2. Integration simplicity and time-to-deployment. Can the vendor integrate with your existing PACS/DICOM workflow in 4 weeks, or 16 weeks? Fractify's native integrations for Epic, Cerner, and GE PACS reduce deployment time significantly. Longer deployments increase your Year-1 costs and delay ROI realization.
3. Clinical support model. Will radiologists have a direct technical contact, or are they routing questions through a help desk? The first model accelerates adoption and confidence. The second creates frustration.
4. Vendor stability and roadmap. Is this a well-capitalized company with multi-year R&D commitments, or an early-stage startup where funding might run out? What's their product roadmap for your clinical domain? Fractify, built by Databoost Sdn Bhd with backing from medical device investors, has a published roadmap for expanding to ultrasound and 3D imaging applications. A vendor with a 3-year product roadmap is lower-risk than one with quarterly pivots.
5. Data privacy and compliance architecture. Does the vendor comply with your regional data residency regulations? Can they operate in fully on-premise mode if required? Fractify supports both cloud and on-premise deployments, with data residency guarantees for institutional compliance.
After Implementation: Tracking True Cost Per Scan in Production
Once your AI radiology system is live, track these metrics monthly to validate your cost model and catch drift:
Observed cost per scan = (Total monthly vendor + infrastructure + staffing costs) ÷ Total scans processed that month
This will drift from your projected cost due to: seasonal volume variations (lower in summer, higher during winter respiratory season), model performance changes, staffing turnover, and infrastructure scaling. Good vendors (including Fractify) provide monthly usage dashboards and cost breakdowns. If your observed cost per scan diverges 20%+ from projected cost after 3 months, investigate:
- Is volume lower than projected? (increases per-scan cost)
- Is the model underperforming and requiring more secondary review? (hidden radiologist cost increase)
- Are you running more compute-intensive processes than planned?
- Did infrastructure costs increase unexpectedly?
Monthly tracking prevents multi-month cost overruns from cascading into unmanageable budget situations. Fractify's customers report 95%+ alignment between projected and observed cost per scan after the first quarter, indicating realistic initial pricing and transparent ongoing cost structure.
ROI Framework: When Does AI Radiology Pay for Itself?
Cost per scan is only meaningful relative to clinical value. Hospitals achieve ROI through three pathways:
1. Improved clinical outcomes (reduced complications, better diagnoses). Detecting missed intracranial hemorrhage, Aortic Dissection, or Acute Stroke earlier reduces patient complications and is valued at $10,000–$50,000 per prevented adverse event. Fractify's brain MRI tumor detection (97.9% accuracy) and intracranial hemorrhage classification (6 subtypes) directly prevent missed diagnoses in high-impact cases. Even 2–3 prevented complications per month covers the annual license cost for a 500-bed hospital.
2. Radiologist productivity (time saved per scan, enabling more scans with same staffing). If your radiologist spends 8 minutes reviewing a brain MRI and AI review reduces this to 4 minutes (due to high-confidence detection and Grad-CAM heatmap guidance), you save 2 minutes per scan. Across 2,000 MRIs/month, that's 4,000 saved radiologist-minutes = 67 hours = 0.8 FTE = ~$180,000/year. This productivity gain typically pays for AI licensing within 3–6 months.
3. Workflow optimization (reduced turnaround time, faster stat findings, reduced ED dwell time). Hospitals using AI-driven urgency scoring for Tension Pneumothorax and Aortic Dissection detection route critical findings to radiologists 40% faster, reducing ED dwell time by 20 minutes per critical patient. For a 400-bed hospital with 30 critical imaging cases/month, this is ~100 prevented hours of ED overcrowding = $30,000+ in ER efficiency value.
Most hospitals realize ROI within 8–18 months when all three pathways are quantified. If you're considering AI radiology and projecting ROI beyond 24 months, reassess your assumptions. You're likely undervaluing clinical safety improvements or overestimating implementation costs.
What does "cost per scan" actually include when vendors quote pricing?
Vendor cost per scan quotes typically include only licensing and inference API access—usually $15–50 depending on modality and vendor. They don't include infrastructure integration ($5,000–60,000), clinical validation ($3,000–15,000), or support ($2,000–8,000/year). True cost per scan must include all eight components: licensing, infrastructure, integration, validation, training, support, compliance, and retraining. Most vendors quote the licensing component only, which is why hospital cost estimates often miss actual total cost by 30–100%.
How do Fractify's pricing and accuracy compare to other vendors?
Fractify charges $20–50 per scan depending on modality, with cloud infrastructure included. Brain MRI tumor detection accuracy is 97.9%, bone fractures 97.7%, and chest X-ray covers 18 pathologies. Pre-validated models reduce your institutional validation costs from $15,000–20,000 to $3,000–5,000. Competitors charging $12–25 per scan often have lower published accuracy (85–92%), requiring 2,000+ scans of your own validation, which costs more in radiologist time than Fractify's premium and lower-cost total-cost-of-ownership model.
Is on-premise or cloud AI radiology cheaper?
Cloud is cheaper for low-volume hospitals (under 500 scans/month). On-premise requires $40,000–80,000 capital investment in GPU infrastructure plus ongoing maintenance. Cloud scales linearly with volume and includes automatic updates, compliance, and uptime guarantees. On-premise scales with hardware additions and requires IT staffing. For high-volume departments (2,000+ scans/month), on-premise can be cost-competitive, but most hospitals find cloud more cost-effective due to infrastructure amortization and support simplicity.
How long does clinical validation take before AI radiology is clinically ready?
Pre-validated models (like Fractify's brain MRI and bone fracture systems) require 300–500 scans of institutional validation, roughly 2–4 weeks. Generic models without institutional validation require 2,000–3,000 scans (8–12 weeks) of radiologist review. The difference is substantial: pre-validated models deploy in 4–6 weeks total; unvalidated models require 12–16 weeks. This time-to-deployment difference impacts Year-1 ROI significantly, with pre-validated models recovering costs 3–4 months earlier.
What does DICOM and PACS integration cost, and why does it vary so much?
DICOM/PACS integration cost depends on vendor architecture. Fractify offers pre-built plugins for Epic, Cerner, and GE PACS, costing $5,000–15,000 and requiring 2–4 weeks. Vendors providing only generic DICOM APIs require custom integration, costing $25,000–60,000 and requiring 8–12 weeks. The variation comes from whether the vendor has already built integrations for your specific PACS system or requires custom development. Fractify's plug-and-play approach significantly reduces integration cost and deployment time compared to API-only vendors.
How does AI radiology model accuracy directly impact the cost per scan?
Model accuracy directly affects radiologist review time and secondary-review workload. A 94% accurate model requires radiologists to review 40% more cases as secondary checks, adding 4–6 minutes per scan in review time. A 97.9% accurate model (like Fractify's brain MRI tumor detection) requires secondary review of only 2–3% of cases. Across 2,000 scans/month, this time difference is worth $5,000–7,500 in radiologist productivity. Higher-accuracy models have a lower true cost per scan when radiologist time is factored into the calculation.
What should we budget for ongoing support and model retraining after deployment?
Budget $2,000–8,000 per year for ongoing support (SLA uptime guarantees, bug fixes, security patches). Budget $4,000–12,000 annually for model retraining and drift detection. Drift occurs when your patient population or imaging protocols shift, degrading model performance. Annual retraining on fresh institutional data (500–1,000 scans) prevents performance degradation. Fractify includes automated drift detection in enterprise contracts, identifying when retraining is needed before clinical performance drops, which prevents costly validation cycles and ensures consistent accuracy across changing patient populations.
How should hospitals compare total cost of ownership when vendors use different pricing models?
Build a three-year total-cost-of-ownership (TCO) calculator including: licensing, infrastructure, integration, validation, training, support, compliance, and retraining. Project your actual scan volume (not optimistic estimates) and model how costs scale with volume growth. Request itemized statements-of-work from each vendor breaking out integration costs, training time, support SLAs, and any optional add-ons that become necessary. Per-scan licensing costs are often 30–40% of true total cost; ignoring infrastructure and integration will underestimate costs by 50%+ and lead to budget overruns.
