CAD, coronary artery disease; LAD, left anterior descending coronary artery; LCX, left circumflex coronary artery; RCA, right coronary artery.

CT-AC, CT attenuation correction; GMPI, gated myocardial perfusion imaging; NAC, nonattenuation correction; RCA, right coronary artery.

P value refers to test accuracy.

P<0.05 for NAC and GMPI.

P<0.05 for CT-AC and GMPI.
