Your PET/CT scan at University College Hospital

A PET/CT scan combines Positron Emission Tomography (PET) and Computed Tomography (CT) imaging. This allows doctors to see both the structure and function of organs and tissues in your body, helping to diagnose and manage various conditions, including cancers, heart disease, and brain disorders.

You will receive specific instructions from the hospital staff, but general preparations include fasting for a few hours before the scan, avoiding strenuous exercise, and informing your doctor of any medications or allergies.

During the scan, you will be asked to lie still on a table that slides into the PET/CT machine. It typically takes about 30 minutes to two hours, depending on the area being examined. You may feel a bit of discomfort from the injection of the tracer.
