Implementation

Questions for IT, informatics, and operations

Use these fields to structure a vendor demo, security review, and implementation estimate.

Integration

Security and privacy
Vendor documentation pending
  • Vendor confirmation
  • Exact FDA submission
  • Checked 2026-09-07

The reviewed sources do not establish exact-release security controls, retention or assurance documentation.

Training and support
Vendor documentation pending
  • Vendor confirmation
  • Exact FDA submission
  • Checked 2026-08-13

Training, onboarding, competency, and support commitments are commercial implementation details that require current vendor documentation.

Monitoring and change control
Vendor documentation pending
  • Vendor confirmation
  • Exact FDA submission
  • Checked 2026-08-13

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.

Evidence

Performance evidence

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.
