qER-CTA (v1.0)

Qure.ai Technologies

Parallel notification of suspected anterior-circulation large vessel occlusion on acute head CTA for specialist review; notification only, not diagnosis.

Evidence status: each field shows source quality, applicability, and review date. Research pending, information not established in reviewed sources, and vendor documentation pending are distinct outcomes.

Clinical fit

What this tool is for

Start with the authorized purpose, then verify how it fits your service line and reading workflow.

Exact purpose
Parallel notification of suspected anterior-circulation large vessel occlusion on acute head CTA for specialist review; notification only, not diagnosis.
FDA source Exact FDA submission Checked 2026-09-08
Intended users
Neurologists, neuroradiologists, radiologists, neuro-interventional specialists, and/or other emergency department physicians
FDA source Exact FDA submission Checked 2026-09-08
Care setting and population
Hospital networks and acute neurovascular clinical workflow
FDA source Exact FDA submission Checked 2026-09-08
Workflow role
Parallel triage and notification support using a passive case-level flag for suspected LVO; the standard-of-care read remains required.
FDA source Exact FDA submission Checked 2026-09-08
Required input
DICOM head CTA images acquired in the acute setting from adults aged 22 and older, targeting the ICA and MCA-M1 for LVO analysis.
FDA source Exact FDA submission Checked 2026-09-08
Output and human action
A case-level passive notification flag available in a PACS or workstation for worklist prioritization, specialist notifications recommending image review, and a compressed informational mobile preview; FDA testing also reports a mean time to notification of 6.36 minutes.
FDA source Exact FDA submission Checked 2026-09-08
Limitations
Compressed mobile previews are informational and not for diagnostic use. The device does not direct attention to specific image portions, rule out LVO, or replace full patient evaluation or diagnosis. It analyzes the specified ICA and MCA-M1 territory in adults aged 22 and older and does not send proactive alerts or change worklist order.

Implementation

Questions for IT, informatics, and operations

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

Integration
For de-identified CTA scans, transmission functions in the PACS or workstation send data to qER-CTA and results return to the PACS or another specified radiology database. A client without de-identification/re-identification can use an on-premises gateway. A mobile app provides compressed previews.

Deployment and data flow
On-premise
Public source Exact FDA submission Checked 2026-08-13

Deployment category preserved from the prior exact-submission review; hosting region, data flow, and current commercial configuration still require vendor confirmation.

Security and privacy
Vendor documentation pending
Vendor confirmation Exact FDA submission Checked 2026-09-08

Exact-release security controls, data retention, hosting boundaries, and scoped assurance documentation require vendor confirmation.

Training and support
Vendor documentation pending
Vendor confirmation Exact FDA submission Checked 2026-09-08

Current training prerequisites, competency checks, and support commitments for the exact configuration require vendor confirmation.

Monitoring and change control
Vendor documentation pending
Vendor confirmation Exact FDA submission Checked 2026-09-08

Current drift, quality, uptime, alert, escalation, and incident-response commitments for the exact configuration require vendor confirmation.

Evidence

Performance evidence

Metrics are shown only when they are tied to a source, endpoint, population, and tested product version.

Evidence summary
FDA standalone clinical testing used 584 head CTA scans, including 289 LVO-positive and 295 non-LVO scans, with ground truth from three U.S. board-certified neuroradiologists. FDA reports AUC 0.959, sensitivity 91.35% (95% CI 87.54%-94.07%), specificity 91.86% (95% CI 88.18%-94.47%), and mean time to notification 6.36 minutes (95% CI 6.06-6.66).

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 K251610. 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.

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.
