The term SPECT scan is used mostly for the brain scanning which detects the comparative areas of the brain function and is most useful for determining areas of brain diminished function, and dementia and alzheimer disease; and also for sequelae of Stroke and brain trauma. The test is under 30 min and much less expensive than a PET scan or Functional MRI which also show these function patterns of the brain. Spect is also used to magnify for more detail in other areas of nuclear scanning such as in the bones and spine and neck.
The SPECT scan technique requires delivery of a gamma-emitting radioisotope (a radionuclide) into the patient, normally through injection into the bloodstream. On occasion, the radioisotope is a simple soluble dissolved ion, such as an isotope of gallium(III). Most of the time, though, a marker radioisotope is attached to a specific ligand to create a radioligand, whose properties bind it to certain types of tissues. This marriage allows the combination of ligand and radiopharmaceutical to be carried and bound to a place of interest in the body, where the ligand concentration is seen by a gamma camera.
The most common uses of SPECT scan are to help diagnose heart problems with stress tests, brain disorders, and spine arthritis and infections.
