ABSTRACT
This study investigated the trabecular and cortical bone microarchitecture of tibia in 14-week-old C3H/HeN, C57BL/6J and ICR mice using micro-computed tomography (micro-CT). Defined volumes of interest were scanned at a resolution of 17 micrometer (isotropic). The X-ray tube was set at photon energy of 50 kV, current of 200 microA, exposure time 1.2 sec, and a 0.5 mm-thick aluminium filter. For quantification of bone mineral density (BMD), the bone samples were scanned by micro-CT together with 2 calibration phantoms. The image slices were reconstructed using 3-dimensional CT analyzer software. C3H/HeN mice showed significantly higher levels of bone volume fraction, trabecular number and BMD, and lower levels of trabecular separation, structure model index and degree of anisotropy compared to C57BL/6J or ICR mice in trabecular bone area. So the C3H/HeN mouse appeared to be a good model animal for the study on the changes of trabecular bone with high trabecular bone mass.
