West Tennessee Imaging Center has the only Positron Emission Tomography (PET) scanner between Memphis and Nashville.

PET/CT is a "Match Made in Heaven." PET/CT scanning is a noninvasive procedure that uses the body's own metabolism to help diagnose and plan treatment for diseases. This is achieved by combining a Nuclear Medicine and CT technique to produce 3-D images. Prior to the PET/CT Scan, a radiotracer (FDG) is injected into the body. The radiotracer consists of part glucose (sugar) and part isotope. The radiotracer metabolizes and emits signals that are recorded. In the case of cancer cells, they have a higher metabolic rate and emit more signals. The PET/CT scanner reassembles the signals into a picture. Brightness within the images measures the amount of activity in various parts of the body. The more activity the brighter the images. The PET portion of the exam locates the metabolic activity. The CT technique pinpoints the exact anatomical location of the organ. Working together, the combination of PET and CT is called fusion imaging.6

Benefits of PET /CT

  • Monitoring the patient response to therapy
  • Thorough diagnosis
  • Improved staging and treatment of cancer
  • Can diagnose a disease before it shows up on other tests
  • Can detect lesions as small as 6 millimeters

PET/CT scans are proven to be effective in diagnosing neurological disease, cardiovascular disease, and a wide range of cancers, as well as other disease processes in the body.
