Abstract Introduction Magnetic resonance imaging MRI may reveal rheumatoid arthritis RA changes in the feet when hands are normal. The purpose of this study was to determine the sensitivity specificity positive predictive value PPV and negative predictive value NPV of a metatarsophalangeal MTP erosion on MRI to predict a subsequent radiographic erosion in the same joint. Similar analyses were performed for bone marrow edema predicting a subsequent MRI erosion. Descriptive results of other lesions are reported. Methods Fifty patients with RA of less than 5 years duration who were rheumatoid .
