Nuclear Medicine

General information

Nuclear medicine scans are safe and non-invasive. Nuclear medicine involves the use of small amounts of radioactive materials (tracer) to help diagnose and treat a variety of diseases.

In this type of test, the radioactive material is introduced into the body by either injection, swallowing, or inhalation. Different tracers are used to study different parts of the body.


The amount of tracer used is carefully selected to provide the least amount of radiation exposure to the patient while ensuring an accurate test. Nuclear Medicine determines the cause of the medical problem based on the function of the organ, tissue or bone.

This is how nuclear medicine differs from an x-ray, ultrasound or other diagnostic tests that determine the presence of disease based on structural appearance. Bone mineral densitometry (BMD) is also provided to patients to determine the bone mineral content and fragility.
