Excised bone structures in mice: imaging at three-dimensional synchrotron radiation micro CT

, : Excised bone structures in mice: imaging at three-dimensional synchrotron radiation micro CT. Radiology 229(3): 921-928

Bone microarchitecture and mineralization were determined at three-dimensional synchrotron radiation micro computed tomography in two inbred mice strains. Distal metaphysis of the left femur was imaged in three dimensions at 6.65 microm, whereas the right femur was analyzed with histomorphometry. Three-dimensional quantitative parameters of trabecular and cortical bone architecture were computed. C3H/HeJ@Ico mice had greater bone density and thicker trabeculae; greater cortical bone density, cortical thickness, and porosity; and greater mineralization than did C57BL/6J@Ico mice. The technique is well suited for assessment of trabecular and cortical bone in small animals and at the same time provides mineralization status in three dimensions.
