Predicting joint damage in rheumatoid arthritis using MRI scanning

Abstract

Predicting prognosis in the patient with newly diagnosed rheumatoid arthritis is of key importance so that high-cost therapies can be tailored to the needs of the individual. In a recent issue of Arthritis Research and Therapy, the prognostic significance of MRI changes at the forefoot has been studied. While progression to radiographic erosion occurred rarely in this group of patients exposed to potent disease-suppressing therapies, including TNF inhibitors, MRI bone edema, representing osteitis, has been further implicated as a forerunner to bone erosion. Early MRI scans of the forefoot were helpful in defining those with the potential to progress as well as those in a good prognosis category. © 2009 BioMed Central Ltd.
