Nuclear Cardiology

Nuclear Cardiology is a busy department which carries out tests on nearly 2,000 patients each year: we are in the top ten busiest departments for Nuclear Cardiology in the UK. The department is well-equipped, with state-of-the-art technology.

Myocardial Perfusion Scintigraphy (MPS)

Small amounts of a radioactive substance (technetium) are injected into the blood stream at peak stress and again at rest.

The isotope can be visualised as it travels through the arteries to the heart, by a special gamma camera (which is not clasutrophobic). The stress can take the form of a treadmill, bicycle or a variety of established intravenous agents. This test looks for heart disease.

Radionuclide Ventriculography (RNV or MUGA).

Small amounts of a radioactive substance are injected into the blood stream to assess overall heart function.

Further details are available from the British Nuclear Cardiology Society website.

At the department

  • One day appointment (including both stress and rest parts)
    Four to five hours in total
  • Two day appointment (stress and rest on separate days)
    Two to three hours each day

We have two separate waiting areas, one for non-injected patients and relatives and another for injected (radioactive) patients. There is television and reading material available. Children should not spend long periods of time in the department.

Our staff will let you know in advance when you are likely to be discharged from the ward, and will discuss with you how you will get home.

You will be given your provisional test results and a full report will be sent to your consultant.

Food and drink

We will 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. We also have a water cooler for patients.
