      Jan, All you need to do is follow the restrictions given by your Drs prior to scans. CTs and MRIs are generally not sensitive to any foods as CTs are just fancy X-rays and MRIs are magnetic scans. PET scans are sensitive to sugars in the blood stream as a PET scan injects you with a radioactive sugar prior to the scan so that areas that are using a lot of sugar light up, thus you will be told to avoid sugars and carbohydates for about 36 hours before the scan. Also remember to smile during the scan, you don't wany them having a bad picture of you!!!!!!!!

      As peroll as so aptly put it, your doctor should tell you what to do and not do before a scan. If you get a CT of your abdomen, you will probably be told not to eat anything after midnight the day before (I usually have my scans first thing in the AM, so if you get one at the end of the day they may let you have breakfast). They may have you stop taking some medications for a day or 2 before and/or after the scan, depending on the medication and the type of contrast they are using.

      Be prepared to "breath in, hold your breath......relax" at least those are the instructions I hear the most when scanned.

      Yeah, your doc should have told you if there was anything to avoid. Call their office and ask if you want to make sure.

      Big Jan, it depends on what type of scan you are having; if you are doing a RAI Scan or RAI avaid scan. As others have said you will want to talk with your dr to see which type of scan you are having. If the scan is an I131 WBS Whole Body Scan for RAI you will be put on a low iodine diet. Allot of people confuse that with a no salt diet, you can use Kosher Salt and non-iodized salt. The diet is basically to limit your iodine input so the thyrca will uptake the iodine and they can see where in your body the thyca is. Here is a link to the cook book that gives you recipes to follow. http://www.thyca.org/Cookbook.pdf
