Detection of mild synovitis with 18F-FDG positron emission tomography (PET) and gadolinium (Gd)-enhanced magnetic resonance imaging (MRI). a Representative transaxial 18F-FDG PET image of rabbit knees. Phytohemagglutinin-induced inflammation had a standardized uptake value (SUV) of 1.20 and the healthy knee had an SUV of 0.75. Representative coronal Gd-enhanced T1-weighted MR images of an inflamed knee (b) and a control knee (c). Red arrows indicate the inflamed synovium and white arrows the control synovium
