The objective of this clinical study was to establish normal values of femur artery dimension using Multi Detector Computed Tomography, and to find the effect of gender on the size of the femoral artery. Abdominal part (aorta at bifurcation) and femoral artery was measured at three sites in the femur of 100 healthy subjects using RadiAnt DICOM viewer system. The study showed that the dimension of abdominal aorta and the right and left femoral artery its slightly bigger in male than female in average it was 16.74 to 16.17 and for right and left side; femoral artery bigger in male than female in average 8.25 to 7.39, all these differences were inconclusive using t-test except the medium (0.047) and upper right femoral artery (0.003). the results also showed that there is strong correlation between the right and left femoral artery; concerning the lower, medium and upper femoral artery 0.78, 0.88 and 0.66 respectively, and in paired t-test there is no significant difference between medium, upper right and left femoral artery at p =0.05while lower part of the femoral artery concerning the right and left side showed significant differences p = 0.02.The important impression in this study is that the diameter of the femoral part (lower, medium and upper) can be estimated from the size of the aorta at bifurcation as normal dynamic, sine the size at bifurcation was normal.
