Bibliography: | Combined the home made PET-MV-2-IT module with carbon-11 methyl iodide module, it was used for synthesis of carbon-11 radiotracers. Methylation agent nC-CH3- Triflate was synthesized with methyl iodide module. The 11C_CH3_Triflate was bubbled to the second reaction vessels in PET-MV-2-IT module, which the precursors were stored. The productions were purified by semi-HPLC and solid phase extraction (SPE) to get the final radiopharmaceuticals. There are four carbon-11 radiopharmaceuticals were synthesized with the method, which it were l lC_Raclopride, 11 C-PIB, 11C-DASB and 11C-PK11195, and synthesis yields were (38.2±4.5)% (n=10),(68.4±3.2)% (n=12), (52.4±5.5)%(n =4)and (45.6±7.1)% (n=8)respectively. All productions radiochemical purity were over 95%. Assembled the methyl iodide module with PET-MV-2-F, which it had semi-HPLC,we can synthesize most carbon-11 radiopharmaceuticals {or clinical used. 11-2566/TL ZHANG Jin-ming, ZHANG Xiao-jun, LIU Jian, CHEN Ying-mao, TIAN Jia-he (Department of Nuclear Medcine , The |
