Multi-spiral CT Diagnosis for Aortic Dissection

Purpose To evaluvate the multi-slice spiral CT (MSCT) technique in diagnosing the aortic dissection (AD). Methods 15 cases with AD were performed by whole aorta MSCT angiography,all data were processed with 2D and 3D reconstructions,the main methods included: MPR,CPR,SSD and MIP. Results All cases were diagnosed as arotic dissection and classified correctly. In 15 cases, true and false cavity, intimal flap, mural thrombus and calcification of AD were displayed. In 12 of all cases, the location of intimal rupture were displayed. The SSD and MIP images of AD displayed the relationship between AD and neighboring organs clearly and directly. Conclusion MSCT is an effective and non-invasive method in diagnosis, classification and location of intimal rupture of AD.
