Nuclear medicine involves noninvasive and usually painless medical tests that help physicians diagnose medical conditions.
In a nuclear medicine exam, a "radiotracer" is injected into a vein, swallowed or inhaled as a gas. It eventually accumulates in the organ or area of your body being examined, where it gives off energy in the form of gamma rays.
What are the advantages?
Nuclear medicine is used to diagnose, manage, treat and prevent serious disease. Nuclear medicine tests are extremely sensitive to abnormalities in organs. They can often identify abnormalities much sooner than other tests can, allowing treatment to start earlier. Earlier treatment can lead to better prognosis.
