Cardiac FDG Viability

Positron emission tomography (PET) cardiology viability imaging is a type of test that measures the way the heart uses glucose - a type of sugar that all cells in the body use for energy. Cells that have been damaged or killed by heart disease or a heart attack will use little or no glucose. Healthy cells and cells that are recovering from injury will use more glucose.


  • To confirm heart damage indicated by other tests
  • To measure how much heart tissue has been damaged by a heart attack or heart disease
  • To tell whether a patient may need angiography, cardiac bypass surgery, a heart transplant, or other procedures

  • Viability Check List:

      ____ 1. Obtain signed order from referring physician with requested scan and diagnosis

    ____ 2. Obtain supporting clinicals - clinical should include one of the following conditions:

  • An imaging radiotracer called FDG (Flurodeoxglucose) is injected into the vein.
  • A brief resting period in a quiet and comfortable environment is provided and required before the imaging begins. This resting period is necessary so that the FDG can be distributed to the heart.

    After the Exam:
    You should experience no discomfort and return immediately to daily activities. Consider bringing food or beverage for yourself after your scan.

    Exam Results:
    The nuclear technologist processes the study. A physician experienced in the interpretation of cardiac studies reads the test. The report is sent to the referring physician who will contact the patient.
