A member asked:
I am required to have a pelvic ct scan once a year as follow-up to colorectal cancer treatment. are double scans without and one with contrast needed?

How long ago: Was your colon or rectal cancer? The protocol for doing with/without contrast (?Vascular and endoluminal?) may be evolving awy from the risk vs need for the without IV contrast. If it is 5 years since, and it was rectal cancer, i would stop scans.

Not usually: Typically a ct scan with contrast only is needed.
