What to Expect

The following information will help you prepare for your appointment at the imaging facility…

  • The scanner rooms can sometimes be cool, so we suggest that you wear warm comfortable clothing. Avoid wearing jewelry or clothes with metal zippers, snaps or fasteners.
  • You will be given specific preparation instructions regarding food, drink and medications.  If you have any questions please call us directly.
  • Refrain from strenuous physical activity for 24 hours prior to your exam, such as working out, jogging, heavy lifting, etc.
  • Bring copies of your most recent CT, X-ray, or MRI films with you on the day of your PET/CT scan.
  • Our scanner is open ended, but if you are concerned because you are claustrophobic please notify your primary physician and or call us for more information.


  • Before arriving at the imaging facility you should carefully follow your specific exam patient prep instructions.  If you are unsure on what they are please call us.
  • Upon arrival to the imaging center, you will be asked to fill out some paperwork.  Be sure to bring you insurance cards, I.D. and a list of the current medications your taking too.
  • You will receive an intravenous injection during your exam.  At what point you receive the injection may vary, depending on your exam.
  • Your scan may last anywhere from 10 – 55 minutes.  The procedure is painless and has no side effects.

How Long Will the Scan Take?

You should plan on spending at least two to three hours at the imaging facility.  The results are interpreted by a trained nuclear medicine physician or radiologist and your physician will receive a written report approximately 24 to 48 hours after completion of the study.


  • PET imaging is a nuclear imaging procedure. All molecular and nuclear imaging procedures are very safe and noninvasive.
  • The amount of radiopharmaceutical used is extremely small, so radiation exposure is minimal. The amount of radiation in most nuclear medicine procedures is comparable to that received during a CT scan.
  • Radiopharmaceuticals are approved by the Food and Drug Administration and prepared with great care.  For more information please refer to the form below.

After Your PET/CT Scan

Once the PET/CT scan is complete, you will be able to leave the imaging facility. Make sure you drink plenty of water or other fluids throughout the day.
