Definition of Scan, SPECT
Scan, SPECT: Single Photon Emission Computed Tomography, a nuclear medicine procedure in which a gamma camera rotates around the patient and takes pictures from many angles, which a computer then uses to form a tomographic (cross-sectional) image.
The calculation process in SPECT is similar to that in CT (X-ray computed tomography) and in PET (positron emission computed tomography).Source: MedTerms™ Medical Dictionary
