PCCT reduced overestimation of coronary artery calcium compared with conventional energy-integrating detector CT (EID-CT), addressing the well-known impact of calcium blooming, partial-volume effects, beam hardening, and motion artifacts on coronary calcium assessment. The study used native coronary arteries from 10…

Cardiac PCCT integrated directly into the acute stroke CT workflow achieved 96% diagnostic accuracy, 90% sensitivity, 97% specificity, and a particularly strong 99% negative predictive value for left atrial appendage (LAA) thrombus compared with TEE. The cardiac acquisition was added immediately after stroke CTA with only…
