This study concern the measurement of the diameter of abdominal aortaat its bifurcation to right and left femur artery, for diabetic patients and hypertensive patients and normal ascontrol group using Multi Detector Computed Tomography MDCT 64 slice. Information was available for 300 patients, 100 patient’s diabetics, 100 hypertensives and 100 normal as a control group, Diameter measurement of abdominal aortic at its bifurcation to right and left femur artery and the study sample diabetic patients and hypertensive and control group a normal; the average diameter of normal femoral artery was (7.96 mm) which is bigger than that of hypertensive patients (7.41 mm) and diabetic (5.91 mm) patients, for abdominal aorta bifurcation of hypertensive patients the diameter was (17.18 mm) which is bigger thanthe normal (16.47 mm) and diabetic patient’s which is (14.89 mm). diameter of abdominal aorta and its bifurcation to left and right femoral artery show that the hypertensive patients showed bigger diameter than the normal and diabetic patients, and the dimension of left and right femoral artery the normal patients showed bigger diameter than hypertensive and diabetic patients.
