here is a quote from CBS news. Now I realize that I am not getting a full body CT just an abdominal one but --
It's not a huge risk, especially for someone with symptoms of a dangerous condition. But when used to screen healthy people for hidden evidence of disease, the risk may outweigh the benefit. And if a healthy person gets repeated full-body scans, cancer risks multiply, Brenner and colleague Carl D. Elliston report in the September issue of Radiology.
"The risks from a single full-body CT scan are not large: If 1,200 45-year-old people got one, you might expect one to die from radiation-induced cancer," Brenner tells WebMD. "But if you are thinking of doing this on a regular basis, as a routine screening modality, then the radiation doses start to add up and the risks then start to get quite high."![]()
One abdominal CT, says the Food and Drug Administration (FDA), exposes a patient to 500 times more radiation than a conventional chest x-ray.

it's not THAT much radiation.... I'd say the benefit outweighs the risk.
When are you supposed to go?
I don't know what you should do, but here is a link to some people who had similar questions/experiences: :::link:::
