We transferred the previously published manual synthesis of [(18)F]ciprofloxacin (decay-corrected RCY: 5.5±1.0%) to an automated synthesis module (TRACERlab(TM) FXFDG, GE Healthcare) and observed a strong decrease in RCY (0.4±0.4%). When replacing the standard 15-mL glassy carbon reactor of the synthesis module with a 3-mL V-shaped borosilicate glass reactor a considerable improvement in RCY was observed. [(18)F]Ciprofloxacin was obtained in a RCY of 2.7±1.4% (n=23) with a specific activity at EOS of 1.4±0.5GBq/µmol in a synthesis time of 160min.
我们将先前发表的[(18)F]环丙沙星的手动合成方法（衰变校正后的放射性化学产率：5.5±1.0%）转移至自动化合成模块（TRACERlab(TM) FXFDG，通用电气医疗集团），并观察到放射性化学产率大幅下降（0.4±0.4%）。当将合成模块的标准15 mL玻璃碳反应器替换为3 mL V形硼硅酸盐玻璃反应器时，观察到放射性化学产率有显著提高。[(18)F]环丙沙星的放射性化学产率为2.7±1.4%（n = 23），在合成160分钟后，终态比活度为1.4±0.5GBq/µmol。
