Positron emission tomography
KEY POINTS • The radionuclides of interest for PET emit positrons, the antiparticles of electrons. • Positrons interact with free electrons to produce two back-to-back 511-keV annihilation photons; PET imaging…
Single photon emission computed tomography
KEY POINTS • Conventional gamma cameras use one to three detectors, based on a NaI scintillation crystal and a photomultiplier tube array, that rotate around the patient. • Cameras commonly…
