SPECT-CT är en hybridutrustning som kombinerar en datortomograf och en tvåhövdad gammakamera. Genom att använda informationen från bilder tagna med datortomografen kan man avsevärt förbättra kvalitet och upplösning i de nuklearmedicinska bilderna och dessutom lokalisera upptag till rätt anatomisk struktur, skelett eller mjukdelar, genom att slå samman de två bildtyperna (bildfusion).

2020-05-07 SPECT/CT showed 6 subjects with false positive results suggesting an adenoma on the wrong side and ultrasound showed 9 subjects with false positive results. SPECT/CT was found to have sensitivity and PPV rates of correct lateralization 92.17% (95% CI: 85.66–96.36%) and … Single-photon emission computed tomography (SPECT, or less commonly, SPET) is a nuclear medicine tomographic imaging technique using gamma rays. It is very similar to conventional nuclear medicine planar imaging using a gamma camera (that is, scintigraphy), but is able to provide true 3D information.

A SPECT scan (single-photon emission computed tomography) is the technique of using nuclear medicine tomographic imaging techniques with gamma rays to provide detailed 3D images of the body. SPECT-CT imaging involves the acquisition of a low dose, non-contrast CT (computed tomography) scan immediately before SPECT (single-photon emission computed tomography) imaging, which uses a rotating gamma camera. It is usually performed in nuclear medicine as an adjunct to standard single plane, gamma camera imaging.
