PDFAbstract
Objective To evaluate the diagnosis value of 16－slice spiral CT in aortic dissection. Methods 40 patients suffering from aortic dissection were examined by contrast-enhanced MSCT. The data were reconstructed by multiplanar reconstruction(MPR), curved planar reconstruction(CPR), volume rendering(VR), maximum intensity projection(MIP). Results According to DeBakey'S classification, DeBakey type I in 5 cases, type II in 2 cases and type Ⅲ in 33 cases were founded in the 40 cases. Enhanced CT scanning and reconstruction can clearly display aortic enlargement, arterial wall calcification as well as true or false cavities, crevasse position and intima stripping range of artery dissection. Conclusion 16-slice spiral enhanced scanning can display the details of aortic dissection. It was a reliable and effective imaging diagnostic way in preoperative evaluation, making the right operative modality and decreasing the perioperative mortality.
