Sustained Macrophage Infiltration upon Multiple Intra-Articular Injections: An Improved Rat Model of Rheumatoid Arthritis for PET Guided Therapy Evaluation

<div>Representative coronal PET images of (a) [18F]FDG and (b)<i> (R)</i>-[11C]PK11195 in arthritic rats group A (6 d). Uptake of both tracers is clearly shown in the right arthritic knee (arrow) compared with the contralateral knee (arrowhead). (c) PET images of [18F]FDG uptake in arthritic rats, original model (left) and group A (6 d) (right).</div>
