Coronary Plaque Quantification with Ultrahigh-Spatial-Resolution Photon-counting Detector CT: Intraindividual Comparison with Energy-integrating Detector CT

Coronary plaque quantification using ultrahigh-spatial-resolution photon-counting detector CT reduced visualized total plaque volume by nearly one-third and improved the reproducibility of low-attenuation plaque measurements compared with that of energy-integrating detector CT.
