Diagnostic nuclear medicine involves the use of radioactive tracers to assess bodily functions and to diagnose and treat disease.
The radioactive tracer is given to the patient by intravenous injection, orally or by other routes depending on the organ and the function to be studied. The uptake, turnover and/or excretion of the tracer substance is then studied with a specially designed camera that allow doctors to track the path of these radioactive tracers. The uptake of the tracer is generally a measure of the organ function or metabolism or the organ blood flow.
