FDA-cleared profile
Riverain Technologies, Inc.
ClearRead CT CAC is image processing software designed to aid physicians in assessing coronary artery calcification on non-gated, non-contrast, standard, or low-dose chest CT scans of adult patients 30 years of age or older. The primary output of ClearRead CT CAC is the Agatston score. ClearRead CT CAC locates calcified coronary lesions and assigns them to one of several coronary arteries: the right coronary artery (RCA), the left main artery (LM), the left anterior descending artery (LAD), and the left circumflex artery (LCX). The software calculates the Agatston score as the sum for each artery while also providing the total across all coronary arteries. The total Agatston score is calibrated to 3.0mm slice thickness and is used to derive a CAC category and the arterial age. The provided segmentations are for illustrative purposes only and are not intended for diagnostic use. ClearRead CT CAC provides adjunctive information and is not intended to be used without clinical expert review.
Clinical fit
Start with the authorized purpose, then verify how it fits your service line and reading workflow.
Exact-submission indication text from the ACR AI Central model card. FDA labeling remains controlling.
Intended-user text reported in the exact-submission ACR model card.
Patient-population text reported in the exact-submission ACR model card; institutional setting may still require vendor confirmation.
Conservative normalization of explicit wording in an exact-submission source.
Conservative normalization of explicit wording in an exact-submission source.
Clinical output reported in the exact-submission ACR model card.
Limitations and supported-acquisition details reported in the exact-submission ACR model card.
Regulatory identity
The FDA listing establishes the regulatory identity. It does not by itself establish local workflow fit, pricing, security, or performance in your environment.
Imaging modality reported in the exact-submission ACR AI Central model card.
Anatomy normalized from explicit exact-submission ACR model-card wording.
Implementation
Use these fields to structure a vendor demo, security review, and implementation estimate.
Interoperability terms explicitly reported in the exact-submission ACR model card; interface versions and local compatibility still require confirmation.
Deployment category preserved from the prior exact-submission review; hosting region, data flow, and current commercial configuration still require vendor confirmation.
FDA authorization does not establish the current commercial security posture. Request data-flow diagrams, hosting and retention details, access controls, audit logging, attestations, and incident-response documentation.
Training, onboarding, competency, and support commitments are commercial implementation details that require current vendor documentation.
Local acceptance testing, production monitoring, drift review, update control, and incident escalation require a current vendor and site-specific governance plan.

ACR AI Central summarizes the regulatory study; consult the exact FDA materials before comparative use.
Economics and lifecycle
These are common procurement questions; unknown values remain visible until a source supports them.
FDA submission materials do not establish current commercial pricing. Request the pricing unit, term, minimum commitment, implementation fees, and included support from the vendor.
Determine whether any product-specific CPT/HCPCS pathway exists and separate it from billing for the underlying imaging service.
Safety and lifecycle
Recall and adverse-event records are shown only after product matching. Adverse-event reports do not establish incidence or causality.
No native submission-identifier match was found in the checked openFDA radiology recall snapshot. Product-name, manufacturer, and adverse-event searches remain necessary; this does not establish that no recall or safety report exists.

Research record
This audit distinguishes completed source review from fields that have not yet been researched.
Exact-submission ACR model-card fields were normalized under the current provenance rules; vendor and independent-study confirmation remain distinct. Automated exact-name discovery found 0 PubMed and 0 ClinicalTrials.gov candidate records. Candidates require human product and version matching; zero candidates is not evidence that no studies exist. Native FDA recall identifiers produced 0 postmarket candidate records; 0 have been reviewed (0 published, 0 rejected) and 0 remain unreviewed.
Candidate leads remain unpublished until a human confirms the exact product and tested version.
