What is a Myocardial Perfusion Scan ?
A myocardial perfusion scan provides a non-invasive method of assessing the blood supply to the heart and also provides information concerning cardiac function.
You will recieve an injection of a medication intravenously that stresses the heart, avoiding the need for walking on a tredmill.
Scans are taken before and after the infusion. This determines the presence of any significant lack of blood to parts of the heart that suggest significant narrowing of the coronary arteries.
It is a highly sensitive and specific test to evaluate the blood supply of the heart. A normal study carries an excellent prognosis.
