Single Photon Emission Computed Tomography (SPECT)
Single-photon emission computerized tomography (SPECT) scans provide three-dimensional images of the interior of your organs using radioactive chemicals and a specialized gamma camera. Healthcare professionals can use this kind of imaging to non-invasively assess the condition of specific body parts, most frequently the heart, brain, and bones.
SPECT scans can display an organ's level of function, which distinguishes them from other imaging techniques. For instance, the SPECT scan images can be used to determine where epileptic patients experience their seizures and to determine whether the various parts of the brain are receiving enough blood flow.
