What is Nuclear Medicine?

Nuclear Medicine is a painless and safe method to scan the body to study structure and function of body organs and bones using radiation from radioactive tracers. Nuclear Medicine procedures often identify abnormalities very early in their progress of a disease long before medical problems are apparent with other diagnostic tests.

How does it work?

Dependent upon the request from your doctor, the procedure involves the injection, swallowing or inhalation of a small amount of a chemical substance tagged with a radioactive tracer – a radiopharmaceutical. The radiopharmaceuticals give off gamma rays and are designed to concentrate in the part of the body being investigated, where there could be an abnormality or disease, e.g. skeleton, lungs, heart or liver. A special camera – a gamma camera then moves around the body, providing a series of images of the radioactivity occurring in that area.

Are the radiopharmaceuticals safe?

Yes absolutely. Like any medicine they are prepared carefully and tested before using on the general public. The risk of side effects is very low. The radiopharmaceuticals commonly used are quickly eliminated from the body through its natural functions.

Is the radiation harmful?

Although radiation exposure in very large doses can be harmful, the radioactivity in radiopharmaceuticals is very minimal and rapidly decreases. The dose is carefully selected to be safe by the Nuclear Medicine technician.
