The micromorphometric variables calculated by the CTAn software (according to the manual Bruker microcomputed tomography (micro-CT) morphometric parameters measured by CT-analyzer software 1.15.4.0 by Bruker micro-CT) [44,45].
| Abbreviation | Variable | Description | Standard Unit |
|---|---|---|---|
| BV/TV | Bone volume fraction | The relative volume of calcified tissue in the selected volume of interest (VOI). | % |
| Tb.Th | Trabecular thickness | Mean thickness of trabeculae, assessed using direct 3D methods. | µm |
| Tb.Sp | Trabecular separation | Mean distance between trabeculae, assessed using direct 3D methods. | µm |
| Po.V(op) | The volume of open pore space | The total volume of all open pores within the VOI is reported. An open pore is defined as any space located within a solid object or between solid objects, which has any connection in 3D to space outside the object or objects. | µm3 |
| Po(op) | Open porosity (percent) | Percent of open porosity is the volume of open pores as a percent of the total VOI volume. | % |
| Po.V(tot) | The total volume of pore space | The total volume of all open and closed pores within the VOI is reported. | µm3 |
| Po(top) | Total porosity (percent) | Percent of total porosity is the volume of total pores as a percent of the total VOI volume. | % |
