How To Prepare

No food for 6 hours prior to study. YOU MAY DRINK WATER, but no other type of liquid is allowed. Please DO NOT chew gum, breath mints, etc.

Diabetic patients may have a light breakfast which may ONLY consist of one egg or egg beaters (no toast, no sweets, sugars or caffeine) 4 hours prior to their scheduled scan time, along with their regular doses of diabetic drugs (insulin, glucophage, etc.). It is also recommended to bring insulin with you in the event that you need it.

No food for 6 hours prior to study for patients with feeding tube.

You may take prescribed medications with water. If any of your medications must be taken with food, ask your doctor whether you should skip your morning dose, take it later in the day, or take it without food on the day of your scan.

Unless you are on fluid restriction for other reasons, drink at least two 8-ounce
glasses of water the night before your scan to prevent dehydration.

Drink two 8-ounce glasses of water the morning of your scan. If your scan is
scheduled for the afternoon, drink several additional glasses of water during the
morning.

Do not perform any vigorous physical activity for at least 24 hours prior to scan.

Patients should wear warm, loose-fitting clothing, such as sweats or flannel shirt.
It will not be necessary to remove any clothing for the PET scan. Do not wear any heavy metal objects or jewelry. Patients must remove any body piercing that has been performed within 4 weeks prior to your scan.

Most PET scans require about an hour of preparation time and about an hour of
imaging time on the scanner. You will be at the PET center for about 2 hours.
The PET scanner machine is similar in shape and size to a CT scanner. Sedation is almost never needed, however, if you are extremely claustrophobic or tend to be extremely nervous and fidgety, consult your doctor about the advisability of taking a tranquilizer before coming to the PET center. If you do require sedation, please arrange to have someone drive you to and from the PET center.
