Reviewed sources checked Exact FDA submission Checked 2026-09-04

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.

• Verify deployment and data flow: Exact deployment topology, hosting, network boundaries, PHI flow, retention, update mechanism, and local operational requirements are not established for this submission.
• Verify security and privacy controls: Public sources reviewed here do not establish the complete exact-release security posture, including identity, audit, encryption, retention, remote access, vulnerability management, backup, or incident response.
• Verify training: Training, onboarding, competency, and support commitments are commercial implementation details that require current vendor documentation.
• Verify pricing and total cost: No public exact-release price, license fee, subscription, contract, or implementation cost was established in this review.
• Verify reimbursement and coding relevance: CMS coverage-index context was checked, but no product-specific coverage or reimbursement determination is inferred.
• 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: 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.

Recovered from the prior exact-submission extraction and normalized under the current provenance rules. Exact-name and exact-submission searches in the checked 2026-09-01 literature and trial indexes returned no PubMed candidate records and no ClinicalTrials.gov candidate records for K233728; the checked openFDA snapshot returned no recall candidate records. Candidate records remain quarantined unless exact product and version linkage is established. Current vendor material is product-family context only. Pricing, complete security architecture, contracted deployment, exact reimbursement, and local interoperability remain unverified. 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.
