Automated radiosynthesis of Al[18F]PSMA-11 for large scale routine use

Abstract Objectives We report a reproducible automated radiosynthesis for large scale batch production of clinical grade Al[ 18 F]PSMA-11. Methods A SynthraFCHOL module was optimized to synthesize Al[ 18 F]PSMA-11 by Al[ 18 F]-chelation. Results Al[ 18 F]PSMA-11 was synthesized within 35 min in a yield of 21 ± 3% (24.0 ± 6.0 GBq) and a radiochemical purity > 95%. Batches were stable for 4 h and conform the European Pharmacopeia guidelines. Conclusions The automated synthesis of Al[ 18 F]PSMA-11 allows for large scale production and distribution of Al[ 18 F]PSMA-11.
