Measuring bone erosion and edema in rheumatoid arthritis: A comparison of manual segmentation and RAMRIS methods

Abstract

Segmentation (outlining) can be used to measure the volume of MRI bone erosion and edema at the wrist in RA patients. When compared with RAMRIS scoring, outlining had similar reliability for quantifying erosions but reliability was lower for bone edema, possibly reflecting difficulty delineating the borders of affected bone.
