AI-based, automated chamber volumetry from gated, non-contrast CT

Cardiac chamber volume is known to be an excellent predictor of future heart failure events. According to recent guidelines, gated, non-contrast cardiac CT (NCCT) is recommended for CAD screening in asymptomatic individuals at low to intermediate risk. We validated a novel, fully automated, AI based method for cardiac chamber volume and myocardial mass quantification from gated NCCT scans used for coronary calcium scoring. NCCT based volume quantification shows excellent agreement with the volumes obtained from CCTA scans in the same patient. Thus, volume assessment from NCCT scans acquired for calcium scoring appears feasible for potential screening.
