T2*-MFX. Quantitative T2* imaging of a 42-year-old male patient 24 months after microfracture therapy of the patella cartilage (marked by arrows). The cartilage repair tissue showed reduced T2* values (ms) and in comparison to the adjacent native cartilage less zonal organization. T2* maps were reconstructed using a multiecho gradient echo (GRE) acquisition, with a TR of 600 ms and 6 TEs of 4.2, 11.3, 18.5, 25.6, 32,7, and 39.9 ms. The field of view was 160 × 160 mm, the pixel matrix was 384 × 384, and the voxel size was 0.4 × 0.4 × 3.0 mm. The bandwidth was 260 Hz/pixel, with 12 slices; total acquisition time was 2:35 minutes.
