Known
also as 'gamma scanning', radionuclide scans detect minute quantities
of gamma radiation emitted by radioactive material injected into the
body. Examples are iodine (in thyroid disorders) and technetium. Tiny
amounts of material are used, as they are specific to a given condition
and concentrate strongly in specific parts of the body. The gamma rays
are collected by a gamma camera, an electronic device which produces
images on a computer. Radionuclide scanning is an invaluable tool for
the early diagnosis of many conditions, especially those affecting function
rather than the structure of organs.
