Procedures for Nuclear Imaging Tests
Nuclear Imaging Procedures
In a nuclear imaging test, the radioactive material is introduced into the body by 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 but ensures an accurate test.
A special camera (scintillation or gamma camera) is used to take pictures of your body. The camera does this by detecting the tracer in the organ, bone or tissue being imaged and then records this information on a computer screen or on film.
Generally, nuclear imaging tests are not recommended for pregnant women because unborn babies have a greater sensitivity to radiation than children or adults. If you are pregnant or think that you are pregnant, your doctor may order a different type of diagnostic test.
