HN CT Sim: with or w/o iv contrast?
So, this tweet came up with a good question: HN radonc Sim CT: with or w/o iv contrast...
If you scroll down the tweet, you will see ppl were making respectful/polite
comments until "our friend Drew" makes a stupid comment, but anyway...
- All HN pts come to me with CT Neck with and w/o iv contrast already done, as well as a PET-CT.
- So, I see no need to inject iv contrast in my dept for 4 reasons:
1. I don't see the need bc I fuse the diagnostic CT with iv contrast into my sim CT (no contrast).
2. It is a hassle to set up iv contrast in a radonc dept (following hosp guidelines and getting an iv injector).
3. I hate to stick my pt with a needle that I don't have to, not to mention risks of further contrast issues
(kidney issues however small it is in the setting of concurrent CDDP).
4. I have done hundreds of HN pts over the years and am very confident to draw GTV/CTV etc.
even w/o contrast. I know my way around the HN regions. Plus I have reviewed the diagnostic CT anyway.
Anyway, this is my practice: diagnostic CT w/ and w/o, PET-CT already done and radonc sim CT (w/o).
I wonder what you guys/gals think...
