Risks of Radionuclide Angiogram (RNA)
Risks of the Procedure
The amount of the radionuclide injected into your vein for the procedure is small enough that there is no need for precautions against radioactive exposure. The injection of the radionuclide may cause some slight discomfort. Allergic reactions to the radionuclide are rare.
If you are pregnant or suspect that you may be pregnant, you should notify your physician due to the risk of injury to the fetus from radionuclide angiography. Radiation exposure during pregnancy may lead to birth defects.
If you are lactating, or breastfeeding, you should notify your physician due to the risk of contaminating breast milk with the radionuclide.
Patients who are allergic to or sensitive to medications, contrast dyes, iodine, shellfish, tape, or latex should notify their physician.
There may be other risks depending upon your specific medical condition. Be sure to discuss any concerns with your physician prior to the procedure.
Nicotine in cigarettes may cause spasm in the coronary arteries, which could affect the test results.
