SPECT & CT - Definitions • SPECT (Single Photon Emission Computed Tomography) – “tomographicscintigraphy where computer generated three dimensional images of radioactive tracer distribution are produced by detection of single photons from acquired multiple planar images” • CT (Computed Tomography) – “tomographic imaging performed with an external x-ray source to derive three dimensional anatomic image data”
SPECT/CT - Definitions Integrated SPECT/CT Systems “that can perform both functions on one gantry and provide fused functional and anatomic data in a single imaging session” “enables a direct correlation of anatomic information and functional information resulting in better localization and definition of scintigraphic findings”
SPECT/CT – pubmed search Hybrid SPECT/CT: the end of "unclear" medicine. Patel CN, Chowdhury FU, Scarsbrook AF. Postgrad Med J. 2009 Nov;85(1009):606-13. “Single photon emission computed tomography/CT (SPECT/CT) is a dual modality technique which increases the sensitivity and specificity of existing radionuclide imaging and helps characterize equivocal lesions detected by other imaging methods.”
