Photon-Counting Detector CT Virtual Monoenergetic Images for Coronary Artery Stenosis Open configuration options

DAIC

82-year-old man with calcified stenosis in left main artery who underwent coronary CTA by PCD CT. Curved multiplanar reformatted images at varying virtual monoenergetic imaging (VMI) levels (40-140 keV) show stenosis at each level. Percent diameter stenosis (PDS) decreased from 92.5% at 40 keV to 53.1% at 140 keV. at 140 keV.
