Tlhaloso ea Sehlahisoa
Metsi a ntlafetseng a Oxygen-18 a sebelisoa e le sepheo se nang le bomo-bared ka thuso ea cyclotron kapa linear accelerator ho hlahisa Flourine-18. Flourine-18 e entsoe ka 2-deoxy-2- 18 F-β-D-glucopyranose (18 F-FDG) e leng molek'hule ea tsoekere e nang le radiolabelled e sebelisoang ho PET (Positron emission tomography) bakeng sa ho fumana libaka tsa metabolism ea glucose e sa tloaelehang le ea sebakeng seo. - ho hlahisa mefuta e mengata ea lihlahala. Kajeno 18 F-FDG ke PET radiopharmaceutical e atileng le e atlehileng ka ho fetisisa. 18 F-FDG ke analogue ea tsoekere, e kenngoa ka har'a vivo ebe 18 F-FDG e tsamaisoa ho tloha maling ho ea ho lisele ka tsela e ts'oanang le glucose. Lisele li monya FDG joalo ka tsoekere empa ha e khone ho fetoloa. Monyetla oa bohlokoa haholo oa FDG-PET ke hore e thusa ho hlalosa ka nepo sethala le libaka tsa lefu le iphetang mefuteng e mengata ea mofetše.
