Objective To investigate clinical value of 64-slice spiral CT in the diagnosis of aortic dissection .Methods 32 patients with aortic dissection in our hos-pital from June 2010 to November 2012 were detected by 64-slice spiral CT and CT scan images were analyzed.Results Before treatment,Specific signs show aortic true and false lumen 31 cases(96.87%),separation within the shift valve 31 cases(96.87%),Nonspecific signs appear as irregular aortic dilatation 32 cases(100.00%), aortic wall thickening and calcification 28 cases(87.50%),mural thrombus 7 cases(21.87%).The diagnostic accuracy rate of 64-slice spiral CT was 96.87%.Con-clusion 64-slice spiral CT diagnosis of aortic dissection can be used as the preferred imaging method,have fast,accurate,convenient and affordable advantages and should be introduced.
