Nuclear Stress Test

Frequently Asked Questions Regarding Ultrasound

Myocardial Perfusion Imaging stress testing is usually done in nuclear medicine departments of a hospital or in cardiac clinics. The test may be performed on an out-patient or inpatient basis. The test involves an injection of radioactive pharmaceutical, a clear radioactive diagnostic liquid for intravenous injection. A small amount of this radioactive pharmaceutical is injected into the bloodstream, where it is taken up into the heart muscle. A special camera is used to take pictures of the heart. From those pictures, your doctor can determine the blood flow to the heart muscle as well as additional structural information about the heart.

*WARNING: *Radioactive pharmaceuticals should not be given during pregnancy unless the potential benefit to the mother outweighs the potential risk to the unborn child. *Radioactive pharmaceuticals may be given to nursing mothers; however, formula should be substituted for breast milk until the radioactive component has cleared the body. Safety and effectiveness in pediatric patients has not been studied..
