Myocardial iodine attenuation is associated with coronary artery stenosis severity: insights from photon-counting CT.
To investigate whether myocardial iodine attenuation and iodine/virtual non-contrast (VNC) ratios derived from photon-counting detector CT (PCCT) are associated with coronary artery stenosis severity as classified by CAD-RADS, and to evaluate their potential complementary value to anatomical grading. In this retrospect...
