Abstract
Objective To evaluate the image quality of 64-slice spiral computed tomography(MSCT)coronary angiography and its diagnostic value for detection of coronary artery stenosis.Methods ①The image quality of reconstructed coronary artery could be divided into five grades,and 100 images were used for evaluation.②32 patients underwent selective coronary angiography(CAG),then results of MSCT were compared with CAG.Results ①The image quality in proximal coronary artery is higher than that in distant artery and 83.6% of all arteries being evaluated.②The accuracy specificity and negative predictive value are high for MSCT in evaluation of arterial stenosis,especially in proximal coronary artery.Conclusion MSCT coronary angiography can be applied as an alternative non-invasive method to CAG in detection of coronary arteriopathy.
