The 44 pages that link to Positron emission tomography, each with the reason it gives.

• Magnetic resonance imagingCompared with: PET emphasizes molecular activity, whereas conventional MRI primarily depicts anatomy and tissue properties.

• Computed tomographyCompared with: PET emphasizes molecular function, while CT chiefly maps X-ray attenuation.

• Medical imagingBroader topic: Tracer uptake displays metabolic activity rather than anatomy alone.

• Beta decayRelated: Its tracers emit positrons through beta-plus decay.

• GlucoseRelated: Fluorodeoxyglucose, a glucose analogue, reveals metabolically active tissues.

• Pair productionCompared with: It uses pair creation’s antiparticle product in reverse: positrons arise from radioactive decay before annihilating.

• Particle physicsBroader topic: It uses antimatter production and detection principles in diagnostic imaging.

• Gamma rayRelated: The positron-annihilation photons detected in PET are gamma rays.

• Functional magnetic resonance imagingCompared with: PET can measure metabolism or molecular targets, but requires a radioactive tracer.

• NeuroimagingRelated: Radiotracers let it map brain metabolism, blood flow, or molecular targets.

• PositronBroader topic: PET turns positron annihilation inside the body into images of tracer activity.

• Serotonin transporterRelated: Labeled ligands can estimate transporter availability in the living brain.

• CyclotronRelated: Cyclotrons produce positron-emitting tracers such as fluorine-18 used in PET.

• AntimatterRelated: It uses antimatter’s annihilation signature to map radioactive tracers in the body.

• Nuclear medicineBroader topic: PET maps radiotracer distribution using coincident detection of annihilation photons.

• LymphomaRelated: PET imaging can show metabolically active lymphoma sites and assess treatment response.

• Charged particleRelated: The scan traces positrons emitted by radioactive tracers inside the body.

• RadiopharmaceuticalBroader topic: PET uses positron-emitting radiopharmaceuticals to map physiological and molecular activity.

• Brown adipose tissueRelated: Fluorodeoxyglucose PET scans helped reveal metabolically active brown fat in adults.

• MagnetoencephalographyCompared with: PET can reveal molecular targets that MEG cannot, but its timing is much slower.

• Image reconstructionBroader topic: Its images are estimated from noisy, indirect coincidence measurements.

• Chest computed tomographyRelated: Combined PET/CT adds metabolic information when evaluating some lung cancers.

• PositroniumRelated: Positronium formation and decay can alter photon timing and provide additional tissue information.

• Scintillation detectorBroader topic: PET scanners commonly use scintillator crystals to detect the annihilation photons.

• Single-photon emission computed tomographyCompared with: PET detects coincident photon pairs, while SPECT detects individual gamma photons.

• Carbon–fluorine bondRelated: The carbon–fluorine bond in fluorine-18 tracers enables widely used PET imaging.

• Electron–positron annihilationBroader topic: It reconstructs tracer locations from pairs of photons produced after positron emission.

• Hodgkin lymphomaRelated: PET scans help stage disease and assess response during treatment.

• RadionuclideBroader topic: It maps the distribution of positron-emitting radionuclides in the body.

• RadiotracerBroader topic: It uses radiotracers to map physiological activity inside the body.

• Technetium-99mCompared with: PET uses positron-emitting tracers rather than technetium-99m's direct gamma emissions.
