PET/CT Scans

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, including early cancer detection and evaluation of treatment response and the diagnosis of various endocrine, neurological, and cardiac conditions.

F-18 FDG (fluorodeoxyglucose) is the PET radionuclide most often used. The images obtained represent glucose metabolism within the body.

The glucose scan is highly sensitive for early detection of malignancies, evaluation of treatment response, and 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.
