Madzi Owonjezera Oxygen-18 amagwiritsidwa ntchito ngati chandamale chomwe chimapangidwa ndi bomba mothandizidwa ndi cyclotron kapena linear accelerator kuti apange Flourine-18. Flourine-18 imapangidwa kukhala 2-deoxy-2- 18 F-β-D-glucopyranose (18 F-FDG) yomwe ndi molekyulu ya shuga ya radiolabelled yomwe imagwiritsidwa ntchito mu PET (Positron emission tomography) pozindikira malo omwe ali ndi vuto la glucose metabolism komanso am'deralo. -kukhazikika kwa mitundu yambiri ya zotupa. Masiku ano 18 F-FDG ndiye PET radiopharmaceutical yofala kwambiri komanso yopambana. 18 F-FDG ndi analogue ya shuga, imabayidwa mu vivo kenako 18 F-FDG imatengedwa kuchokera m'magazi kupita ku minofu mofanana ndi shuga. Maselo amatenga FDG ngati glucose koma sangathe kupangidwa. Ubwino wofunikira kwambiri wa FDG-PET ndikuti umathandizira kutanthauzira molondola siteji ndi malo a matenda obweranso m'mitundu yambiri ya khansa.
