PET–CT

Common card · No. 393089

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) and a computed tomography (CT) scanner, to acquire sequential images from both devices in the same session. The combination of image data are then integrated into a single superposed (co-registered) image that aligns anatomical structures from both imaging modalities into one. Thus, functional imaging obtained by PET, which depicts the spatial distribution of metabolic or biochemical activity in the body can be more precisely aligned or correlated with anatomic imaging obtained by CT scanning. Two- and three-dimensional image reconstruction may be rendered as a function of a common software and control system. PET–CT has revolutionized medical diagnosis in many fields by integrating the ability to improve quality in locating metabolically active regions to functional projection imaging such as CT. For...
