Nuclear Medicine involves the use of small amounts of radioactive materials (or tracers) to help diagnose and treat a variety of diseases.
Nuclear Medicine determines the cause of the medical problem based on the function of the organ, unlike an x-ray which determines disease
based on structural appearance. These exams are safe and painless. Different radioactive tracers are used to study different parts of the body.
They are administered by intravenous injection, swallowing or inhalation. A gamma camera detects the tracer in the organ being imaged and then records the
information on a computer.
