Guide To Positron Emission Tomography Scans (PET Scans)

WebPositron emission tomography (PET) is a gamma imaging technique that uses radiotracers that emit positrons, the antimatter counterparts of electrons. In PET the gamma rays … WebPET scans are often done along with CT scans (called a PET/CT scan) to give more definitive information about metabolism changes and exactly where they are happening in the body. PET works by using a special camera that detects positrons emitted by the radioactive tracer in the organ or tissue being examined. WebFurthermore, SPECT is capable of multi-radioisotope resolution because the energy of the γ-ray photon generated in the de-excitation event depends on the radioisotope used. In PET, the annihilation photons generated by the interactions between positrons and electrons is always 511 keV so it cannot distinguish signal from multiple radiotracer ... buddies appliances weatherford tx
