Example of a normal osteochondral unit obtained using μMRI at 9.4 T. Normal osteochondral specimen of the medial femoral condyle from an ovine stifle joint. Reconstruction in three orthogonal planes: axial (a); coronal (b) and sagittal plane (c). SGE sequence, isotropic voxel with 120 μm x 120 μm x 120 μm allowing multiplanar reconstructions without losing three-dimensional information. Note the minute artifacts (*) in the articular cartilage layer, caused by sample processing, and not resulting from defects of the osteochondral unit. Scale bar = 4 mm.
