What is PET?

Positron-Emission Tomography (PET) is a form of nuclear medicine imaging in which a small, safe amount of radioactive tracer – typically a simple form of glucose called fluorodeoxyglucose – is injected into the bloodstream. The PET scanner visualises the uptake of this tracer to image the tissue and organs in the body and provide valuable information for the diagnosis and treatment of a variety of diseases like cancer, or brain and heart disease.

By using a combined PET and CT scanner, MMI is one of the few practices able to provide high-resolution CT scans at the same time as a PET scan, saving you time and providing the most useful anatomical and functional information to guide treatment.

There is a 7 minute video for you to view located under MMI NEWS entitled:
