Positron emission tomography (PET) is a type of nuclear medicine procedure that measures metabolic activity of the cells of body tissues. Used mostly in patients with brain or heart conditions and cancer, PET helps to visualize the biochemical changes taking place in the body. Since PET is a type of nuclear medicine procedure, this means that a tiny amount of a radioactive substance, called a radiopharmaceutical, is used to assist in the examination. PET is most often used by oncologists, neurologists and neurosurgeons, and cardiologists. Newer technology combines PET and CT into one scanner, known as PET CT. The equipment at the Heptner Cancer Center is a PET CT.

How does it work

  • PET works by using a scanning device (a machine with a large hole at its center) to detect photons (subatomic particles) emitted by a radionuclide in the organ or tissue being examined.
  • The radionuclides used in PET scans are made by attaching a radioactive atom to chemical substances that are used naturally by the particular organ or tissue during its metabolic process.
  • The radionuclide is administered into a vein through an IV. Next, the PET scanner slowly moves over the part of the body being examined and uses the information to create an image map of the organ or tissue being studied. The amount of the radionuclide collected in the tissue affects how brightly the tissue appears on the image, and indicates the level of organ or tissue function.

Why is PET performed?
In general, PET scans are used to evaluate organs and/or tissues for the presence of disease or other conditions. PET may also be used to evaluate the function of organs, such as the heart or brain. The most common use of PET is in the detection of cancer and the evaluation of cancer treatment. More specific reasons for PET scans in cancer treatment include:

  • To detect the spread of cancer to other parts of the body from the original cancer site
  • To evaluate the effectiveness of cancer treatment
  • To detect recurrence of tumors earlier than with other diagnostic modalities
