Comparison of the preparation of the radiopharmaceutical 68Ga-PSMA-11 at two Czech worksites.

Radiopharmaceutical 68Ga-PSMA-11 is one of the newest positron radiopharmaceuticals available for nuclear medicine departments in the Czech Republic. The radiopharmaceutical preparation can be carried out manually or instrumentally using modules for synthesis. Despite the greater technological difficulty of preparation, the success of synthesis of this radiopharmaceutical by both methods is very high, and the evaluated quality parameters of the radiopharmaceutical are comparable by both manual and instrumental preparation methods. Also, regarding professional exposure, the preparation of 68Ga-PSMA-11 does not significantly affect the whole-body and finger dosimetry results.
