Preferred Label : tomography, emission-computed, single-photon;
MeSH definition : A method of computed tomography that uses radionuclides which emit a single photon
of a given energy. The camera is rotated 180 or 360 degrees around the patient to
capture images at multiple positions along the arc. The computer is then used to reconstruct
the transaxial, sagittal, and coronal images from the 3-dimensional distribution of
radionuclides in the organ. The advantages of SPECT are that it can be used to observe
biochemical and physiological processes as well as size and volume of the organ. The
disadvantage is that, unlike positron-emission tomography where the positron-electron
annihilation results in the emission of 2 photons at 180 degrees from each other,
SPECT requires physical collimation to line up the photons, which results in the loss
of many available photons and hence degrades the image.;
