What does it involve?
PET stands for Positron Emission Tomography and it can be combined with computed tomography (CT) to assess both metabolic activity in the body while providing anatomic images of the body, in order to precisely locate areas of abnormal metabolic activity. This is done using a radioactive tracer injected into a vein.
You will need to fast for 6 hours before the scan and you will be asked to avoid certain foods and drinks on the day of your scan. PLEASE CHECK THE LABELS OF ANY FOOD OR MEDICATION. If you are diabetic, it is important to inform the Nuclear Medicine Unit before coming for your scan.
What is it used for?
It is used to look for abnormal energy usage by uptake of the tracer in areas of infection or cancer.
