Evidence status: each field states its source quality, applicability, and review date. Research pending, information not established, and vendor documentation pending remain distinct outcomes.
Product overview
Start with the essentials
Authorized purpose: Parallel triage notification of suspected aortic dissection on contrast CT chest/abdomen; compressed previews are not diagnostic.
Overview status: Source-reviewed overview
What does this software do?Authorized purpose: Parallel triage notification of suspected aortic dissection on contrast CT chest/abdomen; compressed previews are not diagnostic.
Which images or clinical context are in scope?Modality: CT/CTA Anatomy or clinical context: Chest and abdomen; suspected aortic dissection Input: Filtered DICOM contrast CT chest, abdomen, or chest/abdomen exams, including CTA and CT with contrast, from adults or transitional adolescents aged 18 and older; slice thickness 0.5-5.0 mm and adequate field of view are required.
Who uses it?Intended users: Hospital networks and appropriately trained medical specialists
What does the software produce?Output: A priority flag and pop-up notification for suspected aortic dissection in a standalone desktop/image-review workflow, with an unannotated, compressed, low-quality grayscale preview for informational prioritization; the original medical image is not altered.
What is its most important limitation?Key limitation: Not a diagnostic device and preview images are not for diagnosis beyond notification. Full original images in PACS must be reviewed with other patient information and professional judgment. Scope is contrast CT chest/abdomen in patients aged 18 and older, slice thickness 0.5-5.0 mm, excluding inadequate field of view.
Clinical takeaway
Clinical role: Parallel triage notification of suspected aortic dissection on contrast CT chest/abdomen; compressed previews are not diagnostic.
Evidence takeaway
Evidence from the reviewed source record: FDA retrospective blinded multicenter performance testing used 509 contrast CT chest/abdomen cases from five U.S. clinical sites, with ground truth from three senior board-certified radiologists. Primary sensitivity was 92.7% (95% CI 88.2%-95.8%) and specificity was 92.8% (95% CI 89.2%-95.4%) against an 80% performance goal. Secondary mean time-to-notification for true-positive subject cases was 10.7 seconds (95% CI 10.5-10.9), compared with 38.0 seconds for the predicate.

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
A Linux-based server in a cloud environment receives filtered DICOM images, processes series chronologically, and transfers algorithm output to desktop image-review software with pop-up notification and worklist prioritization; diagnostic assessment occurs on original PACS images. Specific local interfaces are not established.
Deployment category preserved from the prior exact-submission review; hosting region, data flow, and current commercial configuration still require vendor confirmation.

ACR exact-submission catalog context
ACR AI Central provides an exact-submission model card for BriefCase-Triage; 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
