ABSTRACT
The standard of reference diagnosis of CAD is the conventional coronary angiography. However its invasive nature necessitates a new non-invasive imaging modality. MSCT coronary, angiography is a new development non-invasive technique in the diagnosis of coronary disease. The aim of this study is to investigate the accuracy of 64-slice CT coronary angiography for assessing coronary artery disease in comparison with conventional coronary angiography. The study included 45 patients out of 50 patients with suspected coronary, artery disease underwent both MSCT coronary angiography and conventional coronary angiography. The total sensitivity and specificity of MSCT coronary, angiography were 99% and 94.5% respectively and the overall accuracy was 95.5%. The negative predictive value was 97.5% while the positive predictive value was 83.5%. Non-invasive CT angiography of the coronary arteries can diagnose and exclude hemodynamically significant coronary stenoses with high accuracy
