Abstract:
Objective To evaluate the diagnostic value and limits of 64-slice spiral coronary artery imaging,by com- parison with selective coronary angiography,in detection of coronary heart disease.Methods Fourty-two patients sus- pected CAD were performed 64-slice spiral CT coronary imaging and selective coronary artery angiography in two weeks, comparative analysis of results were progressed consequently.Results The sensitivity,specificity and positive and nega- tive predictive value to identify≥50% stenosis branches was 90.5%,96.6%,85.9% and 97.8%,respectively.The sen- sitivity,specificity and positive and negative predictive value to identify≥75% stenosis branches was 93.5%,98.9%, 87.9% and99.4%,respectively.Conclusion As a noinvasive quantitative assessment of coronary artery stenoses exami- nation,64-slice spiral CT is a valuable method to detect and diagnose the disease of coronary artery,but its clinical use maybe presently be limited due to image quality in a number of cases.
