ABSTRACT
Multslice CT [MSCT] has proved its importance and applicability in the evaluation of vascular disease including stenosis, occlusion, aneursyms and dissection as well as evaluation of post-traumatic events. The aim of the work will be directed to identify the role of MSCT in the evaluation of aortic lesions. The study will be conducted on patients suspected of having aortic lesions based on clinico- laboratory basis. Each patient will be subjected to thorough history taking, Clinical examination, and MSCT aortography. The advance of cardio-thoracic surgery techniques adds the burden of many questions that need to be answered including the extent, width, and shape of the flap and implication of the coronary arteries and major aortic branches. The presence of leakage is of equal importance in both dissecting and atherosclerotic aneurysms. Evaluation of abdominal aortic aneurysm and leakage by MSCT has proved its usefulness particularly in planning for operative intervention including the length, size of the aneurysm and implication of the major aortic branches. 64 MSCT is an excellent tool for examining the aorta. It gives a great deal of information that, abolishes the need of another diagnostic tool prior to operative intervention. It offers a great mapping of dissecting aortic flap, abdominal aortic aneurysms and coarctation. Time of an essence in dealing with emergency patients and 64 MSCT offers a great portal of diagnosis considering time efficacy and accuracy
