The purpose of this study was to determine whether high-speed T2-corrected multiecho (HISTO) sequences can quantify bone marrow edema (BME) in the capitate bone in rheumatoid arthritis (RA), and whether the HISTO fat fraction (FF) reflects therapeutic effectiveness.

The results showed that the HISTO sequence can measure the bone marrow FF of the wrist joint in RA patients. We also found that the HISTO sequence may help quantify BME in RA and help monitor the effectiveness of RA treatment.
