Overview status: Source-reviewed overview
- What does this software do? Authorized purpose: Viewing, post-processing, qualitative and quantitative evaluation, cardiac measurements, calcium scoring, and evaluation of physician-identified vascular lesions in cardiovascular MR/CT images.
- Which images or clinical context are in scope? Modality: CT/CTA; MRI Anatomy or clinical context: Heart and adjacent cardiovascular vessels Input: DICOM cardiac MR and CT images; semi-automated machine-learning workflows are intended for adults.
- Who uses it? Intended users: Qualified medical professionals experienced with cardiovascular MR/CT images.
- What does the software produce? Output: Four-chamber contouring, coronary calcium scoring, coronary centerlines and stenosis assessment, measurements, reports, and qualitative 3D heart views.
- What is its most important limitation? Key limitation: Only cardiac MR/CT images are in scope; semi-automated algorithms target adults; the 3D heart view is qualitative only; additional exact FDA limitations are unknown.
Clinical takeaway
Clinical role: Viewing, post-processing, qualitative and quantitative evaluation, cardiac measurements, calcium scoring, and evaluation of physician-identified vascular lesions in cardiovascular MR/CT images.
Evidence takeaway
Evidence from the reviewed source record: FDA summary reports 235 anonymized validation images independent from training, with at least 50% from a US population; reported ranges were 97-100% classification, 86-99% calcium classification, 82-94% coronary-centerline performance, and 98-100% mask performance.

Implementation
Questions for IT, informatics, and operations
Use these fields to structure a vendor demo, security review, and implementation estimate.
- Integration
- The exact-submission ACR model card explicitly references DICOM in the described input, output, or workflow; exact interfaces, versions, and local compatibility require confirmation.
Interoperability terms explicitly reported in the exact-submission ACR model card; interface versions and local compatibility still require confirmation.
- Deployment and data flow
- On-premise
Deployment category preserved from the prior exact-submission review; hosting region, data flow, and current commercial configuration still require vendor confirmation.
- Security and privacy
- Vendor documentation pending
Exact-release security controls, data retention, hosting boundaries, and scoped assurance documentation require vendor confirmation.
- Training and support
- Vendor documentation pending
Current training prerequisites, competency checks, and support commitments for the exact configuration require vendor confirmation.
- Monitoring and change control
- Vendor documentation pending
Current drift, quality, uptime, alert, escalation, and incident-response commitments for the exact configuration require vendor confirmation.

Costs and setup
Budget and ongoing governance
These are common procurement questions; unknown values remain visible until a source supports them.
- Pricing and total cost
- Vendor documentation pending
No public price or quote for the exact K213998 configuration was established in this review.
- Reimbursement and coding
- Not established in reviewed sources
No exact-product payer policy, coding instruction, or payment determination was established; eligibility must be evaluated by payer, site of service, and use case.
