Patient Preparation
A radiopharmaceutical injection, which contains a radioactive tracer, is standard for PET/CT exams. For most studies, you will have to wait for the radiopharmaceutical to distribute itself - typically 50 minutes to an hour. Patients will be asked to sit in a quiet, dimly lit room in which to relax while they wait.

To Prepare for your PET/CT Exam
Please follow these special instructions:
- You should not eat anything or chew gum for 4 - 6 hours before your test. Please drink water so you are hydrated.
- If you take medications, you may take them like you normally do with water.
- If you have been advised not to take your medications on an empty stomach, eat nothing more than a few soda crackers within the 4-6 hours prior to your exam.
- If you are a diabetic, let us know ahead of time so we can work out with your physician to determine the safest possible way for you to prepare for your exam.
- If you feel feverish, please call this to our attention.
