Abstract
Objective：To evaluate clinical application value of 64-detector spiral CT angiography for dissecting aneurysm of aorta（ADA）.Material and methods：CT angiography was performed in 41 cases with ADA,Original axial images combined with MPR,MIP and VR were analyzed.Results：The original axial images can diagnose ADA definitely and clearly show true lumen and false lumen（100%）,intimal flap（100%）,entry of intimal tear（90.2%）,the involvement of branches of aortic（51.2%） and thrombosed false lumen（65.9%）,The images of MPR,MIP and VR can show space conditions of aorta and is a very good supplement to the original axial images.The images of MPR can clearly show those entries of intimal tear that the axial images show difficultly,The images of MIP and VR can show the condition of ADA spatially and intuitively.Conclusion：64-detector spiral CT angiography can diagnose ADA definitely and are accurate,quick and non-trauma,so the examination may be as the first choice method in diagnosis of ADA.关键词
