Comparison of SR images and a histological image (G3-histo) in MCP joints of the fourth (panel A) and third digits (panel B). The pathological features of CIA, bony and articular structures including cortical bone thinning (*) and erosion (thick arrow), periosteal bone formation (arrowhead), subchondral bone thinning and disappearance (thin arrow) and destruction of normal articular structure (diamond), could be identified in as much detail in the SR images as in the histological image. MCP: metacarpophalangeal. Scale bar = 500 µm. |
