Your Examination

Prior to your Exam

  • You should avoid any vigorous exercise the day before the exam. Please leave all valuables (jewelry, watches, rings, loose change, or any removable medals) at home. Do not wear clothing that contain metal/metal snaps or metal buttons since metal will interfere with the imaging process.
  • Fast after midnight.
  • Dextrose or TPN should be discontinued at midnight, if that is not possible Dextrose or TPN should be discontinued 5 hours prior to PET scan. (Intravenous glucose infusions are contraindicated)
  • 18-FDG is a radiopharmaceutical, which is administered intravenously; therefore, once you report to PET imaging, intravenous access will be established in the form of a peripheral intravenous line (IV).
  • PIC lines, Mediports, Central lines, or Peripheral temporary venous access, such as that used for chemotherapy administration or dialysis cannot be utilized. Permanent infusion ports cannot be utilized.

During the Exam

  • You will lie on a stretcher or upright chair in a quiet room. Talking during that hour is discouraged, as it affects the distribution of the FDG in your body.
  • Your blood glucose level will need to be checked prior to the injection of the FDG. High serum glucose levels diminish the diagnostic accuracy of this examination. This is especially important for patients who are diabetic; therefore, you should alert the PET imaging department staff if you are a diabetic, prior to receiving the FDG. In some situations, insulin may be administered to lower your blood glucose serum level.
  • In certain cases such as disease in the pelvic/groin area or physician's request, the placement of a urinary catheter may be required. The placement of the urinary catheter will allow continuous removal of urine from be bladder in order to eliminate confusing urinary tract activity from abdominal and pelvic disease.
  • 40 minutes to 1 ½ hour after the injection of the FDG, you will be transferred to the PET/CT Scanner room. We will ask you to lie still while we obtain the images for the radiologist. This may take up to 30 minutes, depending on the exam performed. Please be aware that repeat scans of specific areas of your body may be necessary for diagnostic purposes, this may prolong your examination time.

After your examination

You may resume your previous diet and medication regimen. No special precautions are necessary. A radiologist will read your study and a report will be sent to the ordering physician. If you have any questions please call us.

Please note: If you will be traveling soon after your procedure, please let us know. You may trigger a radiation monitor in a public transportation facility and will need to carry a letter with you regarding your test.
