Abstract: Objective To approach the clinical applied value of MSCT coronary angiography in detecting coronary artery disease. Methods 150 patients underwent MSCT coronary angiography, of them, 100 patients were also examined by coronary arteriography. The ability in showing coronary arteriae with MSCT was evaluated comparatively with coronary arteriography. Results The success-ful rate in showing coronary arteriae by MSCT was 95.3%,the excellent rate of images was 82.970%. There was negative correlation between image quality and heart rate(r=0.938). And the accurate rate in evaluating the narrowing of coronary arteriae was 91.2% with MSCT. There was no significant difference in detecting the narrowing of coronary arteriae with MSCT and coronary angiography (P>0.05). Conclusion By controlling the patients' heart rate(below 70/min) and optimizing the technical methods,MACT coro-nary angiography can detect all of the 1～3 branch of coronary artery. MSCT has some particular superiority in diagnosing coronary artery disease and evaluating the effects of coronary artery bypass graft.
