T1ρ relaxation map overlay of baseline (Left) and 18-month follow-up (Right) for a femoral cartilage lesion progressor with baseline KL = 0 (Female, Age 65). Note the marked increase in relaxation time in the posterosuperior femoral cartilage (arrow), which corresponds to subregion 3.

4. Fig. 3
Sagittal intermediate-weighted MR images demonstrate progression of cartilage loss: at baseline (a) anterior femoral cartilage partial-thickness lesion (arrows) and at 18-month follow-up (b) full-thickness cartilage lesion at the same site (long arrowheads). Opposing anterior acetabular cartilage that was intact on baseline shows new partial thickness cartilage lesion (short arrowheads) at follow up.
