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.
