Complete body PET-CT fusion image Brain PET-MRI fusion image. PET scans are increasingly read alongside CT or MRI scans, with the combination (co-registration) giving both anatomic and metabolic information (i.e., what the structure is, and what it is doing biochemically). Because PET imaging is most useful in combination with anatomical ...
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.
This is a list of positron emission tomography (PET) radiotracers. These are chemical compounds in which one or more atoms have been replaced by a short-lived, positron emitting radioisotope. Cardiology
PET is a functional imaging technique that produces a three-dimensional image of functional processes in the body. The system detects pairs of gamma rays emitted indirectly by a positron -emitting radionuclide ( tracer ), which is introduced into the body on a biologically active molecule.
Types include positron emission tomography (PET) and Single-photon emission computed tomography (SPECT). SPECT is commonly used to diagnose certain diseases. [ 1 ] SPECT imaging is conducting by injecting a radioactive probe (or tracer) into the person's blood stream. [ 1 ]

Positron emission tomography–computed tomography is a hybrid CT modality 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.
