From: Accuracy of magnetic resonance imaging to detect cartilage loss in severe osteoarthritis of the first carpometacarpal joint: comparison with histological evaluation

Fig. 1

Example images of histological grading (a-c) and magnetic resonance imaging scoring (d-f), all from one patient. Arrows (d-f) indicate locations shown in a-c. a, d Cartilage of (near) normal thickness. b, e Partial-thickness loss of cartilage. c, f Full-thickness loss of cartilage. Due to subluxation in the joint, the metacarpal base is not seen in d and e. The quality of the magnetic resonance images was rated as good
