AI Analysis Of Pericoronary Adipose Tissue (PCAT) And Mace Prediction In Non-contrast CT Calcium Score Images

Introduction: We investigated the use of non-contrast CT calcium score (CTCS) images to assess pericoronary adipose tissue (PCAT) and its association to MACE. PCAT features from coronary CTA (CCTA) are well-associated with cardiovascular risk, but are potentially confounded by the presence of iodine. If PCAT in CTCS images can be similarly analyzed, it would allow large population studies and potentially create a new assessment to add to coronary calcium scoring.
