Summary of trabecular microarchitecture outcomes measured by μCT.
Microarchitecture Measurement | Unit | Explanation |
---|---|---|
Percent bone volume (BV/TV) | % | Percentage of area within ROI occupied by bone |
Greater BV/TV is considered positive for bone health | ||
Connectivity density (Conn. D) | mm−3 | Number of redundant connections between trabecular structures per unit volume |
Greater Conn. D is considered positive for bone health | ||
Degree of anisotropy (DA) | No unit | Orientation of the trabecular network, 1-isotropic (lacking orientation), >1 = anisotropic (highly orientated) |
Greater DA is considered positive for bone health | ||
Trabecular number (Tb. N.) | mm−1 | Average number of trabeculae per unit length |
Greater Tb. N. is considered positive for bone health | ||
Trabecular separation (Tb. Sp.) | mm | Average distance between trabeculae |
Greater Tb. Sp. is considered negative for bone health | ||
Trabecular thickness (Tb. Th.) | mm | Average thickness of trabeculae |
Greater Tb. Th. is considered positive for bone health |
