Hoʻohana ʻia ka wai Enriched Oxygen-18 ma ke ʻano he pahu pahu me ke kōkua o cyclotron a i ʻole linear accelerator i mea e hana ai i ka Flourine-18. Hoʻopili ʻia ʻo Flourine-18 i loko o 2-deoxy-2-18 F-β-D-glucopyranose (18 F-FDG) he mole kōpaʻa radiolabelled i hoʻohana ʻia ma PET (Positron emission tomography) no ka hoʻoholo ʻana i nā wahi o ka metabolism glucose abnormal a no ka kūloko. - ka hana ʻana i nā ʻano maʻi he nui. I kēia lā, ʻo 18 F-FDG ka radiopharmaceutical PET ākea a kūleʻa. ʻO 18 F-FDG kahi analogue o ka glucose, ua hoʻokomo ʻia i loko o vivo a laila lawe ʻia ʻo 18 F-FDG mai ke koko i nā ʻiʻo ma ke ʻano like me ka glucose. Hoʻopili nā pūnaewele i ka FDG e like me ka glucose akā ʻaʻole hiki ke hoʻololi ʻia. ʻO kahi pōmaikaʻi koʻikoʻi o FDG-PET ʻo ia ke kōkua i ka wehewehe pololei ʻana i ke kahua a me nā wahi o ka maʻi hoʻomau i nā ʻano maʻi maʻi he nui.
