Figure 1
AB computed tomography image of the cartilage specimen. In (a) and (b) axial sections in different heights of the specimen are shown. Note the lines in the sagittal reconstruction (*). Hypodense areas within the homogeneous main cartilage matrix are clearly depicted in (a), whereas in (b) subchondral bone, trabecular bone and bone marrow vacuoles (thick white arrow) can be identified. A more vertical alignment of the hypodensities in about two-thirds of the cartilage can be seen upon sagittal reconstruction (*). |
