Nuclear medicine

Using small amounts of radioactive material (isotopes) to produce images of the inside of your body.


Nuclear medicine is used for many types of cancers, heart disease, as well as gastrointestinal, endocrine or neurological disorders.

Nuclear medicine exams can be used to identify disease in its earliest stages. They can also be used to show whether you are responding to treatment.

Depending on the area of your body that needs to be examined, an isotope may be injected, swallowed, inhaled or given as eye drops.

A gamma camera picks up the radiation coming from your body, and creates an image which shows areas that are not functioning properly.

How does it work?

The radioactive isotope (radiotracer) accumulates in areas where there is a high level of chemical or metabolic activity – these are called 'hot spots'.

Hot spots can be used to identify uncontrolled over-production of cells caused by cancer.

If there is reduced activity in areas of your body, there will be lower amounts of radiotracer.

These 'cold spots' can be used to identify organs, glands or other parts of your body that are not functioning properly.
