Single Photon Emission Computed Tomography

SPECT, the acronym for Single Photon Emission Computed Tomography, is a nuclear medicine imaging modality, giving information about a patient’s specific organ or body system.

SPECT is used to make three dimensional images of the heart, to perform brain studies and for skeletal scintigraphy. It is reasonable to speculate about a constant by perhaps a slower rate of increase of clinical applications of SPECT. It is safe to conclude that SPECT has reached the stage where it will be a valuable and also an unavoidable asset to the medical world. SPECT is used routinely to help diagnose and stage cancer, stroke, liver disease, lungs disease and a host of other physiological (functional) abnormalities..
