Positron Emission Tomography and Computerized Tomography (PET/CT)

Positron Emission Tomography (PET) and Computerized Tomography (CT) scans, commonly referred to as PET/CT, are a recommended evaluation of many cancer patients. PET/CT scans are very good for most primary head and neck tumors and brain evaluation. PET/CT scans can also be useful for assessing other neurological conditions.

Our PET Center was created jointly with the Department of Radiology.
