The central benzodiazepine receptor (cBZR)-gamma-aminobutyric acid (GABA(A)) receptor complex in the human brain plays an important role in many neurological and psychiatric disorders. (18)F-Labeled flumazenil ([(18)F]FZ) provides a potentially useful tracer to investigate those disorders by means of positron emission tomography (PET).

Improved work-up procedure for the production of [(18)F]flumazenil and first results of its use with a high-resolution research tomograph in human stroke.

Case series with (11)C-PK11195 and positron emission tomography (PET) in stroke patients suggest that activated microglia may be detected in remote brain regions with fiber tract connections to the lesion site as an indicator of poststroke neuroinflammation. However, the specificity of these imaging findings remains to be demonstrated.

Multimodal microglia imaging of fiber tracts in acute subcortical stroke.

Translation of carbon-11 labeled PET tracers to clinical settings is currently impeded by the technical difficulties associated with [C]CO conversion into the highly reactive methylating agents [C]CHI and [C]CHOTf using automated modules relying on stationary valves. Here we describe development of the first in its kind "[C]kit" for production of carbon-11 radiotracer using disposable manifolds. This method proved to be very reliable and allows for consecutive production of PET tracers with minimal intervals between the syntheses.
