Positron Emission Tomography

Positron Emission Tomography (PET) is one of the most advanced and powerful imaging techniques for diagnosing and managing many diseases. PET is a non-invasive procedure that provides unique information about the body’s metabolism, cell function and exact location of disease. This information is not available through the use of CT or MRI, which look at only anatomy or body structure. PET studies body function.

Research has shown that PET can effectively pinpoint the source of many of the most common cancers. PET can give physicians important early information about cardiac and neurological diseases as well. PET often streamlines testing and decreases the need for invasive procedures such as biopsy and surgery. Because PET scans are pictures of the body’s chemistry, many diseases can be seen in their earliest stages.

Important oncology answers PET may provide:

  • Where is the tumor?
  • Is it benign or malignant?
  • Is my treatment working?
  • Has the cancer spread?


Important patient questions PET might answer in heart disease:

  • Does my heart have “live” tissue?
  • Will a by-pass surgery help me?


Important questions PET might answer in neurology:

  • Where do my seizures come from?
  • Will I benefit from surgery to reduce seizures?
  • I have memory loss. Is it Alzheimer’s disease?
