Abstract
Objective To explore the value of multi-slice spiral CT angiography (MSCTA) in the diagnosis of aortic dissecting aneurysms (ADA).Methods 57 cases of ADA in our hospital from April 2013 to October 2016 were selected as research objective,all cases are examined by MSCTA,and the original data were processed by curved planar reconstruction (CPR),multiplanar reformation (MPR),maximum intensity projection (MIP),and shaded surface display (SSD).Analysis of aortic rupture,true and false lumen,intimal flap,the location and extent of aortic dissecting aneurysm,intracavitary thrombosis,and wall calcification were conducted,then compared with diagnosis result of digital subtraction angiography (DSA).Results There were no statistically significant differences in the test results of two kinds of imaging techniques for aortic rupture,true and false lumen,intimal flap,location and scope of aortic dissecting aneurysm,intracavitary thrombosis,wall calcification (P＞0.05),but MSCTA diagnosis had higher accuracy.Conclusion MSCTA can diagnose ADA rapidly,accurately,and safely.It has higher diagnostic value and helps to develop corresponding program timely in clinic,suitable for clinical application.关键词
