Nuclear Medicine Department

What is a Nuclear medicine scan?

In nuclear medicine you will be injected with a small amount of a radioactive ‘tracer’ which travels to the specific part of the body requiring examination. After the injection pictures are taken with a gamma camera.

What does the scan involve?

Once injected, the patient will often have to go off and wait for a period of time before the scan can be done. This gives the injection time to settle in the body.

When brought to the scanner, the patient lies on their back and must stay still for all of the scan. Scans are normally anywhere between 25min-60mins, depending on the area of the body being investigated.
