Scatter plots showing correlations. Correlation seen between (a) magnetic resonance imaging (MRI) bone oedema score and plain radiography (XR) erosion score (r = 0.65, p = 0.0002); (b) MRI bone oedema and MRI erosion score (r = 0.66, p = 0.0002); and (c) MRI bone oedema score and XR joint space narrowing score (r = 0.65, p = 0.0002).
