WebSingle photon emission computed tomography/computed tomography (SPECT/CT) combines two different diagnostic scans into one for a more complete view of the body region being studied. The SPECT scan uses nuclear medicine to give good images of metabolic abnormalities, whereas the CT scan may be able to help narrow down … WebJan 1, 2015 · By contrast, computed tomography (CT) has shown more promising results for attenuation correction of SPECT [9], despite the fact that the energy spectrum of the photons emitted from a CT X-ray tube is polychromatic compared to the monochromatic gamma photons from a radioactive source. Moreover, the photon flux is much higher with CT, …
