PCCT overcomes image limitations for stenosis quantification on CCTA
By Kate Madden Yee
Photon-counting detector CT (PCCT) with virtual monoenergetic imaging reconstruction shows promise for quantifying stenosis with coronary CT angiography (CCTA).
January 10, 2024
82-year-old man with calcified stenosis in left main artery who underwent coronary CTA by PCCT. 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. Extent of calcium blooming artifacts decreased from 100% at 40 keV to 72.3% at 140 keV.

Images in a 55-year-old patient show hepatitis C-related cirrhosis and a transjugular intrahepatic portosystemic shunt (dashed arrow), with an undiagnosed tumor (dashed circle) at pretransplant imaging by both readers. Left: Noncontrast-enhanced axial CT image with a treated observation (dashed circles on the left, middle, and right images) and dense lipiodol staining (arrows) in the anterior right liver. Middle: Late arterial phase CT image with no appreciable enhancement. Right: Delayed phase image with no appreciable washout. The lesion was deemed at explant pathology to have 20% necrosis.
