Nuclear Imaging

Nuclear imaging uses small doses of radioactive substances to help produce images that show activity in various parts of the body. This testing is used for diagnosis and treatment of a number of diseases.

The radioactive substance, which is injected, swallowed or inhaled as a gas,  is attracted to particular organs, bones or other tissues. When the substance releases energy in the form of radiation, special cameras detect the energy and record its movement and location. These cameras rotate around the body and create two- and three-dimensional images of tissues and organs, such as the brain, bones, thyroid, heart, lungs and kidneys.

Examples of nuclear imaging include:
