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?

In brief: Not usually

Typically a ct scan with contrast only is needed.

In brief: 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.
