Following your exam, you should feel fine because there are generally no side effects from the injected tracer. You may immediately return to your normal activities unless the technologist or your physician tells you otherwise.

There is no danger to you or those around you following the exam as a result of the radioactive tracer injection. However, we may advise you to flush twice following urination and to wash your hands thoroughly for a period of time following the exam. Drinking plenty of water may help flush the tracer from your body.

If you are breastfeeding, you should wait at least 12 hours following the exam before breastfeeding again. Follow any specific instructions regarding breastfeeding you receive from your doctor or the PET Center staff (download PDF).

It is essential for you to monitor your condition after you leave our facility. If we gave you intravenous contrast dye for a diagnostic CT scan as part of your PET/CT exam, call your doctor immediately if any of the following occur:

  • Hives
  • Itching
  • Nausea
  • Swollen or itchy eyes
  • Tightness in the throat
  • Trouble breathing

These reactions are rare and would usually occur at the time of contrast dye injection.

Your referring doctor will contact you once the results of your PET/CT are available and ready for review. Your physician should have your results within four business days.
