We evaluated the feasibility of 256-slice MDCT for detecting coronary artery stenosis without beta blocker premedication, and assessed the diagnostic accuracy of MDCT for detecting myocardial ischemia by 201Tl SPECT. Fifty-three patients underwent both coronary CT angiography and stress myocardial perfusion SPECT. All coronary arteries were assessable with appropriate image quality. MDCT revealed high specificity, but only half of stenotic lesion by MDCT revealed ischemia on SPECT.
