AI-Defined Cardiac Anatomy Improves Risk Stratification of Hybrid Perfusion Imaging.

Journal: JACC. Cardiovascular imaging
PMID: 38456877

Abstract

BACKGROUND: Computed tomography attenuation correction (CTAC) improves perfusion quantification of hybrid myocardial perfusion imaging by correcting for attenuation artifacts. Artificial intelligence (AI) can automatically measure coronary artery calcium (CAC) from CTAC to improve risk prediction but could potentially derive additional anatomic features.
