Second-reader support for radiologists reviewing adult digital AP or PA chest radiographs, with suspected pulmonary nodules in the 6-30 mm range marked for review.
Evidence status: each field states its source quality, applicability, and review date. Research pending, information not established, and vendor documentation pending remain distinct outcomes.
Clinical details
What this tool is for
Start with the authorized purpose, then verify how it fits your service line and reading workflow.
Exact purpose
Second-reader support for radiologists reviewing adult digital AP or PA chest radiographs, with suspected pulmonary nodules in the 6-30 mm range marked for review.
Marked suspected pulmonary nodules on the processed image, with the original image presented first and the processed image next in the described workflow.
The product is adjunctive and cannot replace radiologist review. The cleared input is adult frontal AP/PA digital chest radiography; performance and applicability outside that scope were not established here.
The FDA listing establishes the regulatory identity. It does not by itself establish local workflow fit, pricing, security, or performance in your environment.
Use these fields to structure a vendor demo, security review, and implementation estimate.
Integration
Standalone deep-learning software connected to a local radiology network through a DICOM node and PACS; the processed image is returned as a DICOM image for review.
The reviewed sources do not establish exact-release security controls, retention or assurance documentation.

Local acceptance testing, production monitoring, drift review, update control, and incident escalation require a current vendor and site-specific governance plan.
DICOM node and PACS workflow
The cleared configuration connects to a DICOM node and PACS, presents the original image first and then a processed image.
AZmed describes the Rayvolve suite as radiology AI that can be integrated into clinical imaging workflows; the current page does not establish the exact hosting, service levels or version for K243831.
Metrics are shown only when they are tied to a source, endpoint, population, and tested product version. Candidate literature without exact product and version linkage is not shown as product evidence.
Evidence summary
In the FDA-described standalone test of 2,181 radiographs, sensitivity was 0.8847, specificity was 0.8294 and AUC was 0.8408. In a separate 400-case MRMC study, the FDA table reports AUC improvement from 0.8071 unaided to 0.8583 aided, sensitivity from 0.7975 unaided to 0.8935 aided, and specificity from 0.8235 unaided to 0.8510 aided. These are exact-submission study results and not current family claims.

FDA table headings report unaided-to-aided improvement: AUC 0.8071 to 0.8583, sensitivity 0.7975 to 0.8935 and specificity 0.8235 to 0.8510. The source-reported confidence intervals are not reproduced here.

Open questions to take to the vendor
Verify security and privacy controls: The reviewed sources do not establish exact-release security controls, retention or assurance documentation.
Verify training: Training, onboarding, competency, and support commitments are commercial implementation details that require current vendor documentation.
Verify pricing and total cost: No public price or quote for Rayvolve LN was reviewed.
Verify reimbursement and coding relevance: Payer policy research was not part of this worker's scope.
Verify local validation and lifecycle monitoring: Local acceptance testing, production monitoring, drift review, update control, and incident escalation require a current vendor and site-specific governance plan.
Verify recalls and postmarket safety signals: The downloaded exact-ID recall packet contained zero records; this limited result does not establish absence of recall or safety information.
This audit distinguishes completed source review from fields that have not yet been researched.
