Family history of blood pressure related Aortic problems. I have no high BP but cardiologist wants a nearly FULL body CT scan. My understanding is that it is many many times the radiation of a traditional Xray and if they use an ECG (heart rythm synced photographing method) that slows the process to prevent motion blur on image and the XRay exposure is significantly more than even a regular CT scan. Significantly more than a Typical CT. Yikes! I'm only 42 ... doc says CT exposure is overhyped...but I want to get 40more years out of these internal organs such an pancreas, after the CT whereas most of his patients are already only 7-10 years from "it dont matter anymore". And then there is the kidney damaging iodine based contrast they inject. Worried here fellas. Rock and a hard place... Do i get a baseline image of my body which "may" reveal things to watch at the expense of a gauranteed massive radiation exposure and kidney whammy via the contrast?
