What is a Nuclear Myocardial Perfusion Imaging?

​

Nuclear Myocardial Perfusion Imaging is a diagnostic test that uses a small amount of radioactive material and a special camera to create images of the blood flow to your heart muscle. It helps determine if there are areas of the heart that are not receiving enough blood flow.

​

What happens during a Nuclear Myocardial Perfusion Imaging?

 

During Nuclear Myocardial Perfusion Imaging, a small amount of radioactive tracer is injected into your bloodstream. A special camera captures images of your heart at rest and after exercise or medication-induced stress. The procedure can take several hours, including waiting periods between different phases of imaging.

Why would I need a Nuclear Myocardial Perfusion Imaging?

You might need Nuclear Myocardial Perfusion Imaging if you have symptoms of heart disease, such as:

• Chest pain

• Shortness of breath

• Unexplained fatigue

​

Who needs a Nuclear Myocardial Perfusion Imaging?

​

Nuclear Myocardial Perfusion Imaging may be necessary for:

• Patients with symptoms of coronary artery disease

• Individuals with abnormal results from other cardiac tests

• Those needing evaluation of the effectiveness of treatments for heart disease

​

What are the risks of a Nuclear Myocardial Perfusion Imaging?

​

Nuclear Myocardial Perfusion Imaging involves some risks, including:

• Exposure to a small amount of radiation from the radioactive tracer

• Rare allergic reactions to the tracer

• Possible side effects from medications used to induce stress in the heart

​

It's important to note that these risks are rare and the benefits of the test typically outweigh the risks. Additionally, the test is performed under the supervision of trained medical professionals who are equipped to handle any complications that may arise. Your doctor will review your medical history and assess your overall health to determine whether the benefits of the test outweigh the risks for you. If you have concerns about the risks of a stress echocardiogram, discuss them with your doctor before the test.

 

How do I prepare for a Nuclear Myocardial Perfusion Imaging?

​

To prepare for Nuclear Myocardial Perfusion Imaging:

• Follow your doctor's instructions, which may include fasting for a few hours before the test.

• Inform your provider of any allergies and medications you are taking.

• Wear comfortable clothing and shoes suitable for exercise, if applicable.
