As opposed to other imaging methods, PET scans focus on processes and molecular activity in Your system. This gives them the potential to uncover illness in its earliest levels.
As unstable 18-F decays, it releases positrons. Inside of about two mm of journey from their origination internet site in tissue, positrons collide with electrons and release gamma Vitality (photons). The photons strike scintillator crystals housed in a device that encircles the affected individual. Crystals Utilized in modern imaging equipment fluctuate by manufacturer, Every with its possess photon detection produce and backbone; a standard crystal kind employed for PET is lutetium oxyorthosilicate. The crystals transmit the photoelectric Vitality into circuits that transform the electrical energy into Laptop data.
