Imaging Pulmonary Inducible NO Synthase

Inducible nitric oxide synthase (iNOS) activity increases in acute and chronic inflammatory lung diseases. Imaging iNOS expression may be useful as an inflammation biomarker for monitoring lung disease activity. We developed a novel tracer for PET that binds to iNOS in vivo, 18F-NOS. In this study, we tested whether 18F-NOS could quantify iNOS expression from endotoxin-induced lung inflammation in healthy volunteers.
