CorEx

Spimed-AI

CorEx is artificial intelligence software for cardiac imaging. It prioritizes at-risk patients. It automatically analyzes coronary CT images (CCTA) images independently detecting and classifying coronary lesions quantitatively. CorEx automatically classifies stenosis according to the international CAD-RADS classification. CorEx aids the assessment of artery damage and the severity of the obstruction. It also provides an FFR AI prediction: for each coronary the solution predicts if the threshold of 80% is reached or not.

Intended Use Statements
Intended use (according to CE)	CorEx is a standalone software that is intended to be used for viewing and analyzing cardiac computed tomography (CT) data in support for the evaluation of coronary artery disease (CAD). This software post processes CT images obtained using any Computed Tomography (CT) scanner. The software provides visualization of CT scan images, classification of coronary lesions according to their degree of severity (using the international CAD-RADS classification) and can, in the event of a lesion, infer their functional character by estimating the coronary flow reserve (FFR). The results of this analysis are provided to support qualified clinicians to aid in the evaluation and assessment of coronary arteries. The results of CorEX are intended to be used by qualified clinicians in conjunction with the patient’s clinical history, symptoms, and other diagnostic tests, as well as the clinician’s professional judgment.
