Positron emission tomography-computed tomography (better known as PET-CT or PET/CT) is a nuclear medicine technique which combines, in a single gantry, a positron emission tomography (PET) scanner and an x-ray computed tomography (CT) scanner, to acquire sequential images from both devices in the same session, which are combined into a single superposed (co-registered) image Praktische SPECT / CT in de nucleaire geneeskunde - Jones / Hogg / Seeram - Releasedatum: 31 maart 2013 ISBN 978-1447147022 Edition: 2013; Willowson K, Bailey DL, Baldock C, 2008.

Single photon emission computed tomography (SPECT) is a three-dimensional nuclear medicine imaging technique combining the information gained from scintigraphy with that of computed tomography. This allows the distribution of the radionuclide to be displayed in a three-dimensional manner offering better detail, contrast and spatial information than planar nuclear imaging alone With newer devices, a low dose, non-contrast computed tomography (CT) is acquired in conjunction with the SPECT study to produce a fused SPECT/CT image that permits precise coregistration of rCBF with regional cerebral anatomy. This low dose CT scan is not a substitute for diagnostic quality CT or magnetic resonance imaging (MRI)
