Abstract: Objective To explore the diagnosis reliability of the 64-slice spiral CT to the patency of coronary arterial stents after PCI .Methods From September 2009 to December 2012 ,84 patients with 132 coronary artery stents accepted 64-slice spiral CT coronary artetry imaging and coronary angiography .The patency of the stents and the vascular were assessed compared with coro-nary angiography images ,and the diagnostic sensitivity ,specificity and accuracy were analyzed and compared .Results By calculat-ed the number of patients ,the stent occlusion sensitivity and accuracy of 64-slice spiral CT coronary artetry imaging were both 100% .The stent occlusion and stenosis (>50% ) sensitivity ,false negative and positive predictive value were 96 .7% ,3 .4% and 100% .64-slice spiral CT reconstruction imaging of the stent occlusion and stenosis (>50% ) compared with coronary angiography had no statistical difference(χ2 =0 .022 ,P=0 .883) .Conclusion Compared with coronary angiography ,64-slice spiral CT coronary artetry imaging has the higher accuracy and reliability .
