Hi everyone, I’ve been advised to undergo CT Urography both with and without contrast, but I’m concerned about radiation exposure. Since I mostly suspect it’s kidney stones, I’m wondering if there’s a way to reduce the radiation. Would it be possible to first have the non-contrast CT done, then consult with my doctor the following day? If needed, I could then proceed with the contrast CT after the consultation. Alternatively, would it be better to have both scans (with and without contrast) done at the same time?
