Positron Emission Tomography (PET) scanning is a type of medical imaging that provides detailed pictures of what is happening inside the body at the molecular and cellular level.

Molecular imaging offers unique insights that enable physicians to personalize patient care. It provides information that is not available through other imaging technologies or that would require more invasive procedures such as biopsy or surgery.  It is also able to identify and locate disease in its earliest stages, often before symptoms or abnormalities can be detected with other diagnostic tests.

As a tool for evaluating and managing the care of patients, molecular imaging studies help physicians:

  • Determine the extent or severity of the disease, including whether it has spread elsewhere in the body
  • Select the most effective therapy based on the unique biologic characteristics of the patient and the molecular properties of a tumor or other disease
  • Determine a patient’s response to specific medications
  • Accurately assess the effectiveness of a treatment regimen
  • Adapt treatment plans quickly in response to changes in cellular activity
  • Assess disease progression
  • Identify recurrence of disease and help manage ongoing care

Molecular imaging procedures, including PET and PET.CT scanning, are noninvasive, safe and painless.
