Abstract:
Objective To evaluate the clinical value of 64-slice spiral computed tomography(CT) in detecting coronary artery disease. Methods Twenty-three patients with suspected coronary artery stenosis were analyzed by 64-slice spiral computed tomography coronary angiography and catheter coronary angiography. Results Two hundred and ninety -one segments of the two hundred ninety-nine coronary artery segments in twenty-three patients could be visualized by 64-slice spiral CT,eight segments couldn't be visualized because of calcification and exercising shadow. According to gold standard of selective coronary arteriongraphy,the sensibility,specificity,positive predictive value and negative predictive value to diagnose coronary artery stenosis by 64-slice spiral CT were 88.7%,98.2%,94.0% and 96.4%.Conclusion The coronary artery stenosis diagnosis by 64 -slice spiral CT is a potential detecting method and good clinical value but could not replace selective coronary arteriongraphy.
