Abstract
Objective:To investigate diagnostic value of 64-slice spiral CT on patients with coronary artery stenosis disease. Method:124 patients suspected with coronary artery stenosis lesions via clinical diagnosis were selected as research subjects,and retrospective analysis and summary were made according to their clinical data. 64-slice spiral CT coronary artery imaging diagnosis and selective coronary angiography examination were respectively conducted,coronary angiography result was treated as the gold standard,and diagnostic results of diagnosis ways were compared and analyzed. Result:The differences in manifestations of 64-slice spiral CT coronary artery imaging on conditions of coronary artery stenosis(patency,mild stenosis,moderate stenosis,severe stenosis and occlusion)showed no differences when compared to coronary angiography(P>0.05). The sensitivity and positive rat of 64-slice spiral CT coronary artery imaging in the diagnosis of coronary artery stenosis was 98.4%and 63.7%,and indexe of calcified lesions was 96.0%and 61.2%respectively. Conclusion:64-slice spiral CT coronary artery imaging delivers important clinical value in the diagnosis of coronary artery stenosis disease,the image throws certain characteristics,it is provided with advantages including powerful diagnosis ability of stenosis, high diagnostic accuracy,non-invasive examination and accurate positioning,being ideal examination means in the diagnosis of coronary heart disease,and being worthy of clinical service.关键词
