• Positron Emission Tomography/ Computed Tomography (PET/CT) is a hybrid imaging modality that incorporates the use of functional imaging (PET) with anatomical imaging (CT).
  • PET/CT has several valuable clinical applications which include early cancer detection and evaluation of treatment response, and the diagnosis of a variety of endocrine, neurological and cardiac conditions.
  • F-18 FDG (fluorodeoxyglucose) is the PET radionuclide most often used, and the images obtained are a representation of glucose metabolism within the body.
  • The glucose scan is highly sensitive for the early detection of malignancies, evaluation of treatment response and for post-treatment follow-up, more so than the conventional imaging modalities.
  • F18-FDG is produced in Pretoria.
  • Due to the short half-life of the radiotracer, it has to be produced on the same day of the scan, and is couriered to Port Elizabeth via airfreight.
    Each study is interpreted by both a Diagnostic Radiologist and Nuclear Physician.

Branches: Oncology

Preparing for the procedure
  • Specific patient preparation is required before a PET/CT scan can be performed – See link: PET-CT Patient Information Form
  • Bookings can be made at: Bayradiology Cancer Care. Telephone number: 0413630759
  • The PET/CT scanner is situated in Cancer Care (GVI) in 1 Mangold street, Port Elizabeth Cancer Care building.
What to expect during the scan
  • An intravenous cannula will be inserted prior to the scan and the blood glucose will be tested.
  • Blood glucose level is required to be less than 11 mmol/l.
  • FDG is injected in a private cubicle.
  • There is a waiting time of +/- 60 minutes for the radiotracer to distribute throughout the body.
  • The actual scan will vary in length between 20-30 minutes.
