2. Positron emission tomography - Wikipedia

   en.wikipedia.org/wiki/Positron_emission_tomography

   Cardiac PET scanner. [ edit on Wikidata] 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.

   C030. Brain positron emission tomography is a form of positron emission tomography (PET) that is used to measure brain metabolism and the distribution of exogenous radiolabeled chemical agents throughout the brain. PET measures emissions from radioactively labeled metabolically active chemicals that have been injected into the bloodstream.

7. Single-photon emission computed tomography - Wikipedia

   en.wikipedia.org/wiki/Single-photon_emission...

   Single-photon emission computed tomography. Single-photon emission computed tomography ( SPECT, or less commonly, SPET) is a nuclear medicine tomographic imaging technique using gamma rays. [ 1] It is very similar to conventional nuclear medicine planar imaging using a gamma camera (that is, scintigraphy ), [ 2] but is able to provide true 3D ...
