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
AI-assisted acute-care triage and notification of suspected large-vessel occlusion on contrast-enhanced head CTA to prioritize review; not diagnosis.
Contrast-enhanced CT angiography images of the head from patients aged 22 or older suspected of stroke-related circulation occlusion; Siemens and other CT vendors are listed, with exclusions for old infarcts or other brain-vascular disease, metal artifacts, and surgical signs.
A case-level notification of suspected LVO or processing finished, optionally sent to an external notification device; the output does not highlight any portion of the image and does not alter the original medical image.
Intended for patients aged 22 or older and excludes old infarcts or other diseases affecting brain vasculature, metal artifacts such as coils, and surgical signs. The triage output is informational only, not diagnostic, and does not replace review of the original CTA. Standalone validation covered 602 retrospective cases from four U.S. sites.
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
Deployment compatibility is described with the syngo.via platform; DICOM is an applicable software standard and results can be sent to an external notification device. The FDA packet does not establish exact local RIS/PACS interface versions.
Deployment category preserved from the prior exact-submission review; hosting region, data flow, and current commercial configuration still require vendor confirmation.
Exact-release security controls, data retention, hosting boundaries, and scoped assurance documentation require vendor confirmation.

ACR exact-submission catalog context
ACR AI Central provides an exact-submission model card for syngo.CT LVO Detection; FDA labeling remains controlling for clinical use, limitations, and performance.
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
FDA packet: standalone testing used 602 retrospective CT datasets from 602 patients at four U.S. sites, including 307 positive cases with ICA, M1, or M2 occlusions. Two U.S.-board-certified neuroradiologists established ground truth with third-reader adjudication for disagreement. Observed sensitivity was 90.6% and specificity 88.8%; all cases processed in under 110 seconds with a median of 42 seconds.
No contextualized exact-version metric has completed evidence review. Regulatory-document values, when available, are shown above with their limitations.

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 K243145. 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.
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 K243145 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.

Exact-submission ACR model-card fields were normalized under the current provenance rules; vendor and independent-study confirmation remain distinct. Exact FDA scope controls clinical claims. ACR provides bounded exact-submission catalog context. Candidate literature metadata remains a discovery queue until full-text identity, endpoint, population, and version review is completed. 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.
