FDA-cleared profile
CAC Software
Imbio, Inc.
Authorized purpose: Provides non-invasive post-processing to quantify possible coronary calcifications and output Agatston score, arterial age, mass, and volume.
Evidence status: each field states its source quality, applicability, and review date. Research pending, information not established, and vendor documentation pending remain distinct outcomes.
Product overview
Start with the essentials
Authorized purpose: Provides non-invasive post-processing to quantify possible coronary calcifications and output Agatston score, arterial age, mass, and volume.
Overview status: Source-reviewed overview
- What does this software do? Authorized purpose: Provides non-invasive post-processing to quantify possible coronary calcifications and output Agatston score, arterial age, mass, and volume.
- Which images or clinical context are in scope? Modality: CT/CTA Anatomy or clinical context: Heart and coronary arteries Input: Low- or standard-dose DICOM thoracic CT, cardiac-gated or non-gated, with slices up to 3 mm.
- Who uses it? Intended users: Physicians.
- What does the software produce? Output: Color-coded DICOM overlays and a PDF report with total and RCA/LAD/LCx measurements and five-category CAC risk.
- What is its most important limitation? Key limitation: For adults aged 29 years or older and possible calcifications only; contrast, severe motion/metal artifact, and non-thoracic anatomy are excluded.
Clinical takeaway
Clinical role: Provides non-invasive post-processing to quantify possible coronary calcifications and output Agatston score, arterial age, mass, and volume.
Evidence takeaway
Evidence from the reviewed source record: FDA reported a retrospective multicenter assessment of 500 CT series with Cohen's kappa 0.907 (95% CI 0.895-0.920).

- Intended users
- Physicians.
Exact specialty was not established by the packet.
- Care setting and population
- Adult
Patient-population text reported in the exact-submission ACR model card; institutional setting may still require vendor confirmation.
- Workflow role
- Segmentation or contouring
Conservative normalization of explicit wording in an exact-submission source.
- Required input
- Low- or standard-dose DICOM thoracic CT, cardiac-gated or non-gated, with slices up to 3 mm.
Exact FDA input scope.
- Output and human action

Regulatory identity
FDA record and catalog context
The FDA listing establishes the regulatory identity. It does not by itself establish local workflow fit, pricing, security, or performance in your environment.
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 K230112 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.
Safety and lifecycle
Postmarket record
Recall and adverse-event records are shown only after product matching. Adverse-event reports do not establish incidence or causality.
- Postmarket safety review
- The exact-identifier FDA recall query returned no native recall record for K230112. This limited result does not establish absence of recalls or other safety information and does not cover later versions, family records, MAUDE reports, corrections, or field notices.
Buyer worksheet
Open questions to take to the vendor
- Verify security and privacy controls: Exact-release security controls, data retention, hosting boundaries, and scoped assurance documentation require vendor confirmation.
- Verify training: Current training prerequisites, competency checks, and support commitments for the exact configuration require vendor confirmation.
- Verify pricing and total cost: No public price or quote for the exact K230112 configuration was established in this review.
- Verify reimbursement and coding relevance: No exact-product payer policy, coding instruction, or payment determination was established; eligibility must be evaluated by payer, site of service, and use case.
- Verify local validation and lifecycle monitoring: Current drift, quality, uptime, alert, escalation, and incident-response commitments for the exact configuration require vendor confirmation.
