PET scans are easier than an MRI and not noisy! You go in and they check your blood sugar. If all right, they inject you with a radiotracer, Fludeoxyglucose, which checks for cancer. After the injection, you sit quietly without moving or reading for about 45 minutes (some radiologists will let you read and others prefer no movement) and from there they take you to lay down on the table, kind of like an MRI, but you're not actually in a tube. The machine will go back and forth over you. After I have my injection, I just sit with my eyes closed and take a cat nap! The actual imaging takes only about 1/2 to 3/4 of an hour. I've had to have these repeated anywhere from every 3 months to every 6 months and may possibly be going to yearly after my next one. Note: One other thing, they ask that you not do any heavy exercise or movements the day prior. Hope this helps.
