Optoacoustic Imaging and Staging of Inflammation in a Murine Model of Arthritis

Rheumatoid arthritis (RA) is one of the most frequent inflammatory diseases, causing pain and disability in the affected joints. Early diagnosis is essential for the efficiency of symptom‐targeting treatments, but its diagnosis requires careful clinical, serologic, and imaging examinations, such as magnetic resonance imaging (MRI), which is both expensive and time consuming. In an effort to provide the biomedical community with a more accessible way to assess the advancement of arthritis, this study sought to investigate the use of multispectral optoacoustic tomography (MSOT) in a murine arthritis model, to visualize the extent of inflammation in vivo through an L‐selectin/P‐selectin–targeting contrast agent.
