What do I eat the day before? My husband has had several PET scans and was never told to be on any special diet. The only thing he had to do was having nothing to eat or drink 6 hours prior to the scan. He was able to have a few sips of water, since his radiation damaged his saliva glands and his mouth was very dry. If you are diabetic you may need to find out if any special prep.

I was just told not to do any strenuous exercise the day before and to not eat anything. six hours before the test, then drink 16-24 ounces of water about 90 mins before the test. Before the test they take the glucose level before administering the radioactive stuff. that makes the scan light up.

You should plan on spending at least two to three hours at the imaging facility. There is a 60 minute resting period before imaging, and your actual scan will take approximately 15-35 minutes, depending on the type of scan you are having and the type of scanner being used. Diabetic Patients.

There is a different PET scan available, which is used to perform an exam called Myocardial Perfusion PET or Rubidium PET — the preparation for Rubidium PET is very different than for an FDG PET (please see above). FDG PET scans require careful preparation, so please follow instructions carefully. Before Your Study.

I was told, in addition to. I was told, in addition to taking it easy the evening before, to avoid eating too many carbs the prior day. One time the day before having a PET scan, I attended a wedding. It was a bummer to just have to sit still and avoid most of the yummy wedding meal foods.

A PET scan measures body functions like blood flow, oxygen use and the metabolism of glucose, or sugar. Depending on the type of PET scan you have, following a low-carbohydrate diet 12 hours before the scan may be necessary to increase the quality of PET scan images. Foods you can eat are limited for this type of PET scan. Begin your low-carbohydrate diet 12 hours before your scheduled PET scan unless otherwise instructed by your physician, suggests Cedars-Sinai Medical Center. All meats are allowed prior to a PET scan, including beef, chicken, pork and fish.
