Quantification of inflammation in the wrist with gadolinium-enhanced MR imaging and PET with 2-[F-18]-fluoro-2-deoxy-D-glucose.

PURPOSE: To quantify the activity of joint inflammation with magnetic resonance (MR) imaging and positron emission tomography (PET). MATERIALS AND METHODS: Gadolinium-enhanced MR imaging and 2-[fluorine-18]fluoro-2-deoxy-D-glucose (FDG) PET of the wrist were performed prospectively in 12 patients receiving antiinflammatory therapy. Patients were studied three times: off medications for 2 weeks, after 2 weeks of treatment with prednisone or...
