CINA-AD

Aortic dissection is one of the most rapidly fatal cardiovascular emergencies. In Type A dissection, which involves the ascending aorta, mortality without surgical intervention rises by approximately 1 to 2% per hour in the first 48 hours. Type B dissection, limited to the descending aorta, carries lower immediate mortality but can progress to rupture, organ malperfusion, or hemodynamic instability without prompt medical management. In both cases, the time between scan acquisition and the first clinical decision directly affects patient outcome. CINA-AD delivers Stanford classification within seconds of acquisition, so the right team can begin preparation before the radiologist has opened the full case.

CINA-AD analyzes chest and thoraco-abdominal CT angiography to flag suspected aortic dissection, delivering a notification with Stanford classification (Type A or Type B) and four preview slices. In the standalone performance study (n=289), mean time-to-notification was 22.7 seconds. CINA-AD does not alter the original image and is not intended as a diagnostic device.

The Stanford classification divides aortic dissection into Type A (ascending aorta, emergency surgery required) and Type B (descending aorta, medical management first). The classification determines which clinical team needs to mobilize and how urgently. Knowing it at the moment of detection, before the full report, allows the appropriate team to begin preparation immediately.
