1) Dot 
A special type of computed tomography (CT) scan in which a small amount of a radioactive drug is injected into a vein and a scanner is used to make detailed images of areas inside the body where the radioactive material is taken up by the cells. SPECT can give information about blood flow to tissues and chemical reactions (metabolism) in the body. ...

Type: Abbreviation Pronunciation: spekt Definitions: 1. Acronym for single photon emission computed tomography.
SPECT: An acronym that stands for 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 tomogra...

Single-Photon Emission Computerized Tomography involves scanning involving the rotation of detectors around a patient and acquires information on the concentration of radionuclides introduced to the patient's body. This is analogous to CT imaging with x-rays See also PET.
