About Us 2017-05-11T14:30:28+00:00


The P.E.T. Fusion Imaging physicians are board certified radiologists from FWRadiology. Our physicians have specialized training in PET/CT interpretation.

Positron Emission Tomography (PET) and Computerized Tomography (CT) Fusion Imaging is the most effective diagnostic imaging tool used in oncology. It allows physicians to make an earlier and more accurate diagnosis that will aid your doctor in designing the most effective treatment plan for you.

A PET scan allows a radiologist to see the activity or growth of cells in the body by detecting metabolic changes in cancer cells. At the same time, a CT scan provides a detailed internal picture allowing physicians to determine the precise location of the cancer. When combined, the PET/CT exam provides physicians with the essential information needed to diagnosis and treat your cancer.
