What happens before a resting and exercise radionuclide angiogram (RNA)?

A resting and exercise radionuclide angiogram (RNA) is a type of nuclear medicine procedure that evaluates the heart's chambers in motion. Before the procedure:
  • Your physician will explain the procedure to you and offer you the opportunity to ask any questions that you might have about the procedure.
  • You will be asked to sign a consent form that gives your permission to do the test. Read the form carefully and ask questions if something is not clear.
  • Generally, no prior preparation, such as fasting or sedation, is required. In some cases, smoking cigarettes may be restricted two or three hours before testing.
  • If you are pregnant or suspect that you may be pregnant, you should notify your physician.
  • Notify your physician of all medications (prescription and over-the-counter) and herbal supplements that you are taking.
  • Notify the technologist or physician if you are allergic to or sensitive to medications, local anesthesia, contrast dyes, iodine, or latex.
  • Notify your physician if you have a pacemaker.
  • Based upon your medical condition, your physician may request other specific preparation.
