sharaxaada alaabta
Biyaha Oxygen-18 ee la xoojiyey ayaa loo isticmaalaa sidii bartilmaameed kaas oo bam-barded iyadoo la kaashanayo cyclotron ama xawaaraha toosan si loo soo saaro Flourine-18. Flourine-18 waxaa lagu dhex sameeyay 2-deoxy-2-18 F-β-D-glucopyranose (18 F-FDG) taaso ah unug sonkor ah oo shucaac ah oo loo isticmaalo PET -qabashada noocyo badan oo burooyin ah. Maanta 18 F-FDG waa dawada ugu faafsan uguna guulaha badan PET radiopharmaceutical. 18 F-FDG waa analooga gulukooska, waxaa lagu duraa vivo ka dibna 18 F-FDG ayaa laga soo qaadaa dhiiga loona gudbiyaa unugyo si la mid ah gulukoosta. Unugyadu waxay u nuugaan FDG sida gulukooska laakiin lama dheefi karo. Faa'iidada aadka muhiimka ah ee FDG-PET waa in ay si sax ah u qeexdo marxaladda iyo goobaha cudurrada soo noqnoqda ee noocyo badan oo kansar ah.
