Background: The aorta consists of an ascending segment, a transverse segment or arch, and a descending segment consisting of descending thoracic aorta and descending abdominal aorta. Material and methods: The study group included 52 patients including 32 males and 20 females of age ranging between 6 yrs to 65yrs. The patients underwent computed tomographic aortic angiographic scan for various indications, at 64-slice CT center of the Department of Radio diagnosis. Results: In the present study, we found that the diameter at the level of T12 ranged from 10mm to 28.3 mm with a mean value of 17.77± 3.48 mm. Conclusion: The knowledge of the diameters of abdominal aorta at various levels can help in effective diagnostic tool in a case of abdominal aortic aneurysm and also for the endovascular treatment of abdominal aortic aneurysm by vascular endograft implantation. Such more type of study required more region wise.
