Figure 2:
There was a significant difference in SUVmean (not shown), SUVmax, Ki, K1, and extraction fraction between healthy and osteoarthritic subchondral bone [A-D]. There was also a significant difference in SUVmean (not shown), SUVmax, K1, and extraction fraction between bone that appeared structurally normal in healthy knees (“Normal Healthy”) and in OA knees (“Normal OA”) [E-H]. * = p < 0.05, ** = p < 0.01, *** = p < 0.001.
