摘要:
The present invention relates to technetium imaging agents comprising radiolabeled c-Met binding peptides suitable for SPECT or PET imaging in vivo. The c-Met binding peptides are labelled via chelator conjugates. Also disclosed are pharmaceutical compositions, methods of preparation of the agents and compositions, plus methods of in vivo imaging using the compositions, especially for use in the diagnosis of cancer.
摘要:
System and method for monitoring a synthesis process in a synthesizer to provide reduced quality control efforts and facilitate quality by design. The system and method perform by detecting a synthesizer parameter value for one or more synthesizer parameters of a radiopharmaceutical synthesis process in a radiopharmaceutical synthesizer, and comparing the synthesizer parameter value of each of the synthesizer parameters to a corresponding reference synthesizer value range. The radiopharmaceutical synthesis process is either continued, aborted, or interrupted based on a comparison result.
