Radioactive tracers are used in imaging tests that help
find problems inside the body. These tracers give off particles that can be detected
and turned into a picture to help find problems in organs or other structures.
tracer is usually given through an intravenous (IV) line placed in a vein. But the
tracer also may be given by mouth or by inhaling it into the lungs. The tracer then
travels through the body and may collect in a certain organ or area.
of tests that use radioactive tracers include positron emission tomography (PET) and
nuclear medicine scans to look at specific organs such as the liver, lungs, kidneys,
