Positron Emission Tomography CT

The Benefits

Positron Emission Tomography (PET) is a highly specialized non-invasive imaging procedure that is used to assess the level of metabolic activity in various organ systems in your body. This scan will also be combined with a CT scan. These scans will be completed simultaneously while you lie on the table. Intravenous Contrast dye will not be given for this exam. Oral contrast will be administered, as tolerated. Having both of these scans done at the same time will provide information about the structure and function of your organs.
