William Beaumont Army Medical Center conducted its first positron emitted tomography (PET) scan recently. The PET/CT camera, most advanced in the region, acquires and fuses PET data and computed tomography (CT) data simultaneously. The technology uses a lower dose of radiotracer, reducing radiation exposure to patients. Overseeing the project and scanning of the first patient was Maj. Kevin Schlegel, a nuclear medicine physician. The PET information shows metabolism (glucose use) in the body and the CT reveals the anatomy.  PET is mainly used to identify abnormal hypermetabolic processes in the body such as cancer, infection and inflammation.
