Myocardial Perfusion Scintigraphy (MPS)

This test looks for coronary artery disease. A small amount of a radioactive substance (Myoview-Tc99m or Thallium-201) is injected into the bloodstream at peak stress, and again at rest.

The distribution of this tracer, as it travels through the coronary arteries to the heart muscle, can be visualised by a highly sensitive scanner called a gamma-camera.

The stress can take the form of exercise on a treadmill or bike. Patients with mobility issues are given an infusion of an established intravenous pharmacological stressing agent.

We then analyse the images and send them to the referring consultant.

Radionuclide Ventriculography (RNV or MUGA)

A small amount of a radioactive substance is injected into the bloodstream to assess regional heart muscle contraction and overall heart pumping function.

Your appointment

A one-day appointment (including both stress and rest parts) is four to five hours in total

A two-day appointment (stress and rest on separate days) is two hours each day

We have two separate waiting areas, one for non-injected patients and relatives and another for injected (radioactive) patients.

Our staff will let you know in advance when you are likely to be allowed home and will discuss your transport options with you.

Food and drink

We ask you to eat and drink something to help to clear the radioactive agent out of your system. This improves the quality of the scan. You might like to bring some food and drink with you from home.

Some refreshments are available to buy within the hospital and we also have drinking water for patients.
