Abstract:
ObjecfiveTo explore clinical value of 64-slice spiral CT coronary angiography in diagnosing coronary atherosclerotic heart disease. as compared to that with selective coronary angiography.MethodsOne hundred and thirteen patients who underwent both 64-slice spiral CT coronary angiography as well as selective coronary angiography at an interval of no more than one month at Zhongshan Hospital.Shanghm in 2006 were selected for the study and their imaging reports were analyzed and compared.ResultsImages of 910 segments of coronary arteries were collected and assessed.Sensitivity,specificity and likelihood ratio for negative test result of 64-slice spiral CT coronary angiography in diagnosis of coronary atherosclerotic heart disease were 73.8 percent.97.0 percent and 24.4,respectively,with an overall agreement of 93.2 percent,positive predictive value of 82.7 percent and negative predictive value of 95.0 percenL ConclusionsSixty-four-slice spiral CT coronary angiography has hish specificity,negative predictive value and positive likelihood ratio,with high accuracy,in diagnosing coronary atherosclemtic heart disease.
