Photon-Counting CT Shifts Cardiac Imaging Beyond Stenosis to Atherosclerosis Assessment

Photon-counting CT enables multi-dimensional coronary assessment—plaque, inflammation, physiology, and myocardium—in a single exam, moving from stenosis-centered to disease-centered imaging.

• Five key PCCT enhancements: ultra-high-resolution stenosis/stent evaluation, refined plaque characterization, perivascular fat inflammation analysis, CT-derived physiology, and myocardial mapping (ECV, late iodine enhancement).
• The technology may challenge the roles of diagnostic invasive angiography and cardiac MRI in selected scenarios, pending clinical validation.
