A method in which images are generated by using radionuclides that emit single photons of a given energy. Images are captured at multiple positions by rotating the sensor around the subject; the three-dimensional distribution of radionuclides is then used to reconstruct the images. SPECT can be used to observe biochemical and physiological processes, as well as the size and volume of structures. ...

| single photon emission computed tomography |
A noninvasive scanning procedure during which a radioactive substance known as a radionuclide is introduced into the body to help evaluate the function and structure of certain organs or tissues. The amount of the substance taken up by particular tissues may depend upon the amount of blood flow within such regions. For example, absence of radionuclide uptake in a targeted region may indicate a lack of blood flow in certain areas. ...

| single photon emission computed tomography |
An imaging technique that measures the emission of photons of a given energy from radioactive tracers introduced into the body. As with other forms of computer-assisted tomography, the technique produces a series of cross-sectional images of internal anatomy.
