2. Positron emission tomography - Wikipedia

   en.wikipedia.org/wiki/Positron_emission_tomography

   Positron emission tomography (PET) [1] is a functional imaging technique that uses radioactive substances known as radiotracers to visualize and measure changes in metabolic processes, and in other physiological activities including blood flow, regional chemical composition, and absorption.

3. PET-CT - Wikipedia

   en.wikipedia.org/wiki/PET-CT

   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.

4. PET-MRI - Wikipedia

   en.wikipedia.org/wiki/PET-MRI

   PET-MRI systems don't offer a direct way to obtain attenuation maps, unlike stand-alone PET or PET-CT systems. [32] [33] Stand alone PET systems' attenuation correction (AC) is based on a transmission scan (mu - map) acquired using a 68 Ge (Germanium-68) rotating rod source, which directly measures photon attenuation at 511 keV.

5. Medical imaging - Wikipedia

   en.wikipedia.org/wiki/Medical_imaging

   PET images can be viewed in comparison to computed tomography scans to determine an anatomic correlate. Modern scanners may integrate PET, allowing PET-CT, or PET-MRI to optimize the image reconstruction involved with positron imaging. This is performed on the same equipment without physically moving the patient off of the gantry.

6. PET radiotracer - Wikipedia

   en.wikipedia.org/wiki/PET_radiotracer

   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.
