Abstract:
Objective To evaluate the diagnostic value and technique advantage of 16-slice CT angiography(16SCTA) in aortic dissection.Methods 39 cases of aortic dissection underwent 16SCTA.The data were reconstructed by multiplanar reconstruction(MPR),curved planar reconstruction(CPR),volume rendering(VR),maximum intensity projection(MIP),virtual endoscopy(VE),and generally analyzed in combination with original axial images.Results According to DeBakey's classification,DeBakey's type Ⅰ in 5 cases,type Ⅱ in one case and type Ⅲ in 33 cases were founed in the 39 cases.16SCTA clearly showed that including the ture and false lumen(39 cases,100%),intimal flaps(39 cases,100%),intimal tear(25 cases,64.1%),and thrombus inside the false lumen(17 cases,43.6%).Conclusion 16SCTA may be as the first choice method in diagnosis of aoric dissection,and which is considered as having great value.
