Medical Application - Positron Emission Tomography

PET Labs is situated at the Little Company of Mary Hospital In Groenkloof, Pretoria, South Africa. Positron Emission Tomography, an imaging modality in nuclear medicine, is performed here.

Nuclear medicine imaging is a unique, safe and effective technique that provides physicians with information of both the structure and the function in a patient's body. It is a non-invasive, painless way to do diagnostic tests and enables the physician to identify abnormalities in a very early stage of a disease, even before any symptoms may have occured.
Only extremely small amounts of radiopharmaceuticals are used which are detected by special cameras that are linked to computers to betray accurate images of the part of the body being diognised.

The chemicals produced at PET Labs are: FDG (Fluorodeoxyglucose(18F), FDOPA (Fluorodopa(18F) and FLT (Fluorothymidine(18F). These chemicals are produced by proton bombardment of 18-O enriched water in a cyclotron. The half-life of 18-F is 109.8-minutes which indicates that rapid transport and administration to the patient is needed.
