Not at all, I think I would be concerned too if I read I have a moderate to severe atherosclerotic calcification of the aorta and bilateral iliac vessels, it's mean you may not be getting enough oxygenated blood to your legs and organs. I know I would be all over both the doctor that ordered the test and your vascular surgeon, they owe you some answers.
Let us know how it works out and good luck............JON
