There is currently a need for a cost-effective imaging technique to aid in the early diagnosis of rheumatoid arthritis, a crucial factor in improving patient outcomes. Optical molecular imaging (OMI) is currently used to image tumors for diagnostic and surgical applications, but can be adapted for imaging cellular and sub-cellular processes that are a part of other diseases. This article reviews how researchers at the University of Michigan used OMI to image inflammation in the mouse CAIA model, with promising implications for clinical usage.
