▪ imaging technique
imaging technique used in biomedical research and in
diagnosis. SPECT is similar to
positron emission tomography (
PET), in which a compound labeled with a
positron-emitting radionuclide is injected into the body; however, its pictures are not as detailed as those produced using PET.
SPECT is much less expensive than PET because the tracers it uses have a longer half-life and do not require an accelerator nearby to produce them. It can be used to diagnose or evaluate a wide range of conditions, including diseases of the
heart,
cancer, and injuries to the
brain.
