incazelo yomkhiqizo
Amanzi e-Oxygen-18 athuthukisiwe asetshenziswa njengethagethi evinjwa ngebhomu ngosizo lwe-cyclotron noma i-accelerator eqondile ukuze kukhiqizwe i-Flourine-18. I-Flourine-18 ihlanganiswe ibe yi-2-deoxy-2- 18 F-β-D-glucopyranose(18 F-FDG) okuyi-molecule kashukela ene-radiolabelled esetshenziswa ku-PET (Positron emission tomography) ukuze kutholwe amasayithi e-glucose metabolism engajwayelekile kanye neyendawo. -ukwenziwa kwezinhlobo eziningi zezimila. Namuhla i-18 F-FDG iyi-PET radiopharmaceutical esabalele futhi eyimpumelelo. 18 I-F-FDG iyi-analogue yeglucose, ijovwa ku-vivo bese i-18 F-FDG ithuthwa isuka egazini iye ezicutshini ngendlela efana neglucose. Amaseli amunca i-FDG njengeglucose kodwa awakwazi ukugaywa. Inzuzo ebaluleke kakhulu ye-FDG-PET ukuthi isiza ukuchaza ngokunembile isigaba nezindawo zezifo eziphindelelayo ezinhlotsheni eziningi zomdlavuza.
