A novel 18F- labelled compound suitable for use as a PET tracer for imaging GABA receptors is provided as well as a precursor compound for use in its synthesis and methods for its preparation. Also disclosed herein is an in vivo imaging method comprising administration of said 18F- labelled compound, which finds use in the diagnosis of conditions in which expression of the GABAA receptor is abnormal, or in the monitoring of such conditions.

tomography (PET) using the tracer [11C]Flumazenil has shown changes in the distribution and expression of the GABAA receptor in a range of neurological conditions and injury states. We aim to develop a fluorine-18labelled PET agent with comparable properties to [11C]Flumazenil. In this study we make a direct comparison between the currently known fluorine-18labelled GABAA radiotracers and novel imidazobenzodiazepine
