Myocardial Perfusian Scan
A nuclear medicine myocardial perfusion scan provides information about your body to help with your diagnosis and treatment.
The myocardial perfusion scan is a non-invasive imaging test that shows how well your heart muscle is being supplied with blood. It is sometimes also called a technetium scan or a thallium scan.
Tracers, which are substances containing a small amount of radioactivity, are used to highlight different areas of the body depending on the test being carried out.
