Nuclear Cardiology

A Cardiac Nuclear Scan, also known as Myocardial Perfusion Imaging provides valuable information about your coronary arteries and heart muscle. It is used to evaluate symptoms that are suspicious for blockages in the arteries that supply oxygen-rich blood to your heart muscle. Pictures are taken of your heart using a radioactive medicine.

How do I prepare for the procedure?

• Do not eat or drink anything for 12 hours prior to your appointment time.
• Take any prescribed medication unless otherwise directed by your physician.
• Wear comfortable clothes and shoes for exercising and imaging.

Myocardial perfusion imaging is combined with another diagnostic technique called the stress test.

The stress test can be performed employing several methods such as walking on a treadmill, or combined with a “chemical” test and slow treadmill walk. The “chemical” stress test is most often performed at our facility with Adenosine or Dobutamine in case there are patients who are not able to exercise (orthopedic disease or chronic lung disease, etc.).

Is It Safe?

The radiation exposure during a Cardiac Nuclear Scan is small, and the doses used are safe. However, if you are pregnant, suspect you may be, or are a nursing mother, be sure to let your doctor know.
