Summary

Millions of patients undergo PET (positron emission tomography) imaging every year, but there is a critical unmet need for new PET imaging probes capable of diagnosing and monitoring a multitude of diseases. One of the most versatile radionuclides for PET imaging is 18F, but rapid chemical synthesis of any probe based on 18F is essential because its physical half-life is only 110 min. Huiban et al. (1) recently reported an improved method for labeling trifluoromethylarenes (Ar-CF3) with 18F that could greatly facilitate the development and adoption of new PET probes and allow the site of action of existing drugs to be identified.
