Coronal proton density MRI wrist scans. A) Baseline MRI scan (2009) shows cartilage thinning at the radiolunate (score = 2 ) and radioscaphoid joints (score = 1) (arrowheads) B) At 3 years (2012), the cartilage space narrowing has progressed; radiolunate score = 3 and radioscaphoid joint score = 3 (arrowheads). A new erosion (white arrow) is also now seen to involve the triquetrum at the site of bone oedema at baseline.
