Original X-ray angiogram of the left hindlimb vasculature in a control mouse. Femoral arteries were visualized by bolus intra-arterial injection of iodinated contrast agent. Femur and tibia are also evident. Closed-circles placed on the arteries indicate the points, which were measured for inner diameter. The numbers are corresponding to the arteries averaged for vessel diameters in Table 1. Scale bar = 1 mm
