Why is a resting radionuclide angiogram (RNA) performed?

A resting and exercise radionuclide angiogram (RNA) is a type of nuclear medicine procedure that evaluates the heart's chambers in motion. Reasons for your physician to request a radionuclide angiography include, but are not limited to, the following:
  • chest pain
  • shortness of breath
  • dizziness
  • fatigue
If a screening examination (such as an electrocardiogram or ECG) suggests a possibility of some type of heart disease process that needs to be explored further, a resting and exercise RNA may be performed. There may be other reasons for your physician to recommend resting and exercise RNA.
