Perfusion scans 

MPS/CMRI

Myocardial perfusion scan

A small amount of radioactive substance is concentrated in the heart to create images which show blood flow to the heart muscle.

Also known as a thallium scan, MIBI scan, technetium scan or nuclear medicine scan.

The myocardial perfusion scan looks at the pumping action of your heart and the flow of blood to your heart muscle. It can help diagnose coronary heart disease and may also be used by doctors to find out if you’d benefit from a coronary angioplasty or coronary bypass surgery.

What it shows

A myocardial perfusion scan allows a measurement of the pumping action of your heart (ejection fraction) and shows the distribution of blood flow through the heart muscle. It helps in diagnosis of coronary heart disease. The results often show if there may be benefit from revascularisation by coronary angioplasty or bypass surgery.
