Mean differences (SD of differences) and Pearson correlation coefficients (r) for cartilage volume (VC) and mean cartilage thickness over the total area of bone (ThCtAB.Me) for (A) FLASH versus DESS-MPR and (B) FLASH versus DESS from the pooled data. Team E did not use identical regions of interest for FLASH versus DESS for medial tibia (MT) and lateral tibia (LT) and their data was eliminated from the comparison in these plates. For comparison of FLASH versus DESS ThCtAB.Me, exclusion of one team with individual femoral correlations below 0.88 substantially increased the pooled correlations (r=0.90–0.91).
