ABSTRACT
Objective :To study and observe application value of 256 slice spiral CT coronary imaging (MSCT) for di‐agnosing coronary artery stenosis in aged patients .Methods :A total of 95 aged patients suspecting coronary artery stenosis treated in our hospital were selected .They received MSCT and coronary angiography (CAG) respectively . Inspecting outcomes of above two diagnostic methods were comprehensively compared .Results :(1) CAG identified 91 positive cases and four negative cases in diagnosing coronary artery stenosis ,while it's 89 positive cases and six negative cases for MSCT .The diagnostic outcomes of two methods were highly consistent (Kappa= 0.789 , P=0.001 ) ,suggesting MSCT can achieve the diagnostic effect of CAG ; (2) Sensitivity ,specificity ,positive predictive value ,negative predictive value and accuracy of MSCT diagnosing coronary artery stenosis was 94. 51%,25.00%, 96. 63%,16.67% and 91.58% respectively ,suggesting diagnostic outcomes of MSCT possessed high accuracy ; (3) There was no significant difference in judgment of coronary artery stenosis degree between MSCT and CAG , P=0.524. Conclusion :The diagnostic accuracy of 256 slice MSCT is high in aged patients with coronary artery stenosis , which is almost consistent with that of the gold standard‐CAG .The conduction is simple and it's noninvasive ,which can be extended in clinic ;but it′s specificity is compare less ,must pay suitable intension
