Abstract The role of cyclooxygenase (COX)‐2 as a driving force in early tumourigenesis and the current interest in the combination of COX‐2 inhibitors with standard therapy in clinical trials creates an urgent need to establish clinically relevant diagnostic tests for COX‐2 expression. Molecular imaging using small‐molecule probes radiolabelled for both positron emission tomography (PET) and single photon emission computed tomography (SPECT) offers the potential to meet this need, providing a minimally invasive readout for the whole disease burden. This review summarises current approaches to the radiolabelling of small‐molecule COX‐2 inhibitors and their analogues for PET and SPECT imaging, and gives an overview of their biological evaluation and likely success of clinical application.
