Parallel notification of a suspected large-vessel occlusion
Dieser Text steht auf Englisch, bis eine Übersetzung vorliegt.
Viz.ai ContaCT analyzes brain CT angiography and can text a neurovascular specialist when it suspects a large-vessel occlusion, in parallel with the usual read. FDA permitted marketing in 2018 as notification software. The specialist still reviews full images on a diagnostic workstation. The product is not a diagnosis and not a treatment decision.
Klinischer Rahmen
Emergency stroke imaging, for adults who already have a CT angiogram as part of a stroke workup, inside a hospital network that has a specialist on call.

FDA described a retrospective set of 300 CT angiograms reviewed against neuro-radiologists, plus real-world evidence aimed at earlier specialist notification. This card does not restate a sensitivity figure. The labeled limit is notification, not a stand-alone read.

This is an illustrative composite, not a trial report. As the triage nurse types the chief complaint and first vitals, a model suggests an acuity level. The nurse accepts or overrides it, and the accepted level is the one that enters the queue. The scenario is about keeping a human on the decision when under-triage would delay care. No accuracy percentage is claimed, because this entry is not a study.
IDx-DR, now marketed as LumineticsCore by Digital Diagnostics, was authorized to screen adults with diabetes for more-than-mild diabetic retinopathy without an eye specialist reading the photo first. A primary care team captures images on a specified retinal camera and the software returns a refer-or-rescreen result. It is not a complete eye examination. Pregnancy and several existing retinal conditions sit outside the labeled use.

The MASAI trial in Sweden randomly assigned screening mammograms to AI-supported reading or standard double reading without AI. Transpara scored each exam and routed lower scores to a single reader and the highest score to double reading, with detection marks available on higher-risk exams. This card quotes the prespecified interim safety analysis, not a claim that every screening program should switch.
