Comparison of compositional MRI techniques to quantify the regenerative potential of articular cartilage: a preclinical minipig model after osteochondral defect treatments with autologous mesenchymal stromal cells and unseeded scaffolds.

As expected, dGEMRIC is well suited for monitoring cartilage regeneration. Interestingly, T imaging also proved to be a reliable cartilage imaging technique and thus offers a contrast agent-free alternative to the former gold standard for subsequent studies investigating the cartilage regeneration potential of different treatment modalities.
