Ingcaciso yeMveliso
Amanzi e-Oxygen-18 aphuculweyo asetyenziswa njengento ekujoliswe kuyo ibhom-barded ngoncedo lwe-cyclotron okanye i-accelerator ye-linear ukwenzela ukuvelisa i-Flourine-18. I-Flourine-18 idityaniswe kwi-2-deoxy-2-18 F-β-D-glucopyranose (18 F-FDG) eyimolekyuli yeswekile ene-radiolabelled esetyenziswa kwi-PET (i-Positron emission tomography) ukumisela iisayithi ze-glucose metabolism engaqhelekanga kunye neyendawo. -ukwenziwa kweentlobo ezininzi zamathumba. Namhlanje i-18 F-FDG yeyona nto isasazeke kakhulu kwaye iphumelele iPET radiopharmaceutical. I-18 F-FDG yi-analogue ye-glucose, ifakwe kwi-vivo kwaye emva koko i-18 F-FDG ihanjiswa ukusuka egazini ukuya kwizicubu ngendlela efana ne-glucose. Iiseli zifunxa i-FDG njengeglucose kodwa ayinakwenziwa i-metabolized. Inzuzo ebaluleke kakhulu ye-FDG-PET kukuba inceda ukuchaza ngokuchanekileyo inqanaba kunye neziza zesifo esiphindaphindiweyo kwiintlobo ezininzi zomhlaza.
