Objective To investigate the 64 - slice spiral CT in the diagnosis of aortic dissection value ; compare 3D imaging VRT freedom cut into images and CTVE with other post-processing method of the intimal tear above the level of the celiac axis display rate ; aortic dissection involving the celiac level , true and false aortic dissection cavity diagnosis and differential diagnosis . Materials and methods of data collection from the First Affiliated Hospital of Suzhou University and Suzhou Kowloon Hospital , Shanghai Jiaotong University School of Medicine , January 1, 2007 and April 09 , 2010 , 2010 and 163 cases of patients with the diagnosis of aortic dissection diagnosed ; underwent 64 slice spiral CT angiography . Results in 1,163 cases of aortic dissection in 87 patients , including 63 cases of 19 cases of De Bakey I , De Bakey II five cases , De Bakey type III ; 19 cases of true aneurysm , 11 patients with mural thrombus ; false three cases of aneurysm , arteritis , aortic atherosclerosis associated with the mural thrombus four cases , pulmonary thrombosis , pulmonary inflammation , thickening of the pleural adhesions , gallstones , cholecystitis , bowel obstruction , aortic lesions 9 patients , no significant positive lesions in 37 patients. 2 , the post-processing of cross-sectional images at five in the intimal tear display capabilities with significant differences in descending order transverse binding CTVE. , VRT freedom cut into like , MPR display rate of the intimal tear transection surface , VR, MIP. 3 , a branch of the level of the celiac axis blood supply or involvement by the false lumen , the true lumen is usually also visible entrance by the re- entrance to the appropriate branch of the blood supply , and then toward the entrance edge intimal arterial branches , each branch by the true lumen of the blood supply will not see again each branch condition of the blood supply and the entrance to the distribution of the true and false lumen in 39 patients with aortic dissection to identify with the whole observation or surgery confirmed the match . Conclusion 1,64 layer spiral CT cross-section and its various post- treatment imaging technology is fast , accurate , non-invasive , comprehensive aortic lesions make the diagnosis . 2, CTVE stereoscopic display intuitive break location combined with transverse images can increase the rate of the breaches show ; VRT the freedom cut into like the lacerations display rate than the VR significantly improved , with the MPR have the same effect , or even superior to the MPR . 3 , various branches of the blood supply to the level of the celiac axis and the entrance to the distribution of important clinical value in the identification of the true and false lumen of aortic dissection , and help to identify the region 's re- entrance .
