Integrating AI quantitative CT, photon-counting CT, and FFR-CT brings coronary plaque burden and ischemia assessment into one CCTA workflow
This review surveys recent advances in coronary CT angiography (CCTA) for coronary artery disease: AI-driven plaque and stenosis quantification can cut analysis time from over 25 minutes to typically under 60 seconds per case with correlation coefficients of 0.92-0.95 against intravascular ultrasound, photon-counting detector CT (PCD-CT) reduces calcium blooming at ultra-high resolution and reclassifies some cases to lower CAD-RADS categories, and FFR-CT adds noninvasive lesion-specific physiologic assessment, so that combining the three can support more refined risk stratification for major adverse cardiovascular events and preventive therapy decisions.
