Myocardial Perfusion Scan With Exercise (Overview)

Myocardial perfusion imaging looks at blood flow to the left ventricle. This is primarily accomplished using nuclear techniques such as pet or spect using radiotracers such as tl-201, tc-99m, or n-13 ammonia. When it is done with exercise, the myocardial perfusion scan shows blood flow during exercise, and usually compares that to perfusion at rest in order to evaluate for inducible ischemia.

What is the purpose of a myocardial perfusion scan?

Nuclear stress test: This is a specialized form of stress test used to confirm the presence of coronary artery disease in patients suspected of having this problem. It uses a low-level nuclear tracer to assess blood flow to the heart muscle before and after exercise-induced stress. In patients who cannot exercise, other pharmacologic means can be used such as adenosine, lexiscan, persantine, or dobutamine. ...Read more

What is the function of a myocardial perfusion scan?

Blood flow to heart: It shows blood flow to the heart. It can show old scar of a heart attack or heart muscle that is not getting enough blood , which could mean a future heart attack. ...Read more

Can I eat food before having myocardial perfusion scan?

Can I eat food before having myocardial perfusion scan?

No: No because the blood flow to stomach increased and it makes the image less accurate. ...Read more

Why would someone be scanned both front side and back during the myocardial perfusion scan?

The diaphragm: The position of the diaphragm can change depending upon whether you are lying down prone or supine. Scanning from both directions is sometimes used to minimize interference from the diaphragm when imaging the heart. ...Read more

Are there any medical complications from myocardial perfusion scan that would cause coughing?

No: The scan itself should not cause a cough. However, you may experience a cough after performance of a stress treadmill test (due to exercise induced asthma) or performance of pharmacologic stress (due to dilation of pulmonary vessels). ...Read more

Are there any side affects after having a myocardial perfusion scan if so can you tell me please?

Are there any side affects after having a myocardial perfusion scan if so can you tell me please?

Radiation...: Depending on what radiotracer is used, you will be exposed to a small amount of radiation but the benefits of the test should outweigh the risks. Are you having pharmacologic or exercise test? Some of the pharmacologic agents can cause some side effects such as bronchoconstriction but a medication called aminophylline can usually be administered to reverse the side effects. ...Read more

What are the risks in having a myocardial perfusion scan?

What are the risks in having a myocardial perfusion scan?

Stress associated : A myocardial perfusion scan is performed in two steps. One injection of a radiotracer at rest and another at stress ( either treadmill or pharmacological stress test with adenosine, regadenoson, dobutamine, dipyridamole). Only few skin reactions have been reported with the radiotracer injection. Risks are more associated with the stress used for the test such has angina, headache, nausea... ...Read more
