It provides precise measures of 3-D microstructural morphometric details and volumetric density of the cortical and trabecular components of bone (Figure 1), with minimal radiation exposure (&lt; 3 μSv per scan)1. Therefore, HR-pQCT has the potential to identify and quantify early microstructural bone quality changes before permanent bone damage has occurred. To date, HR-pQCT has been used to assess bone quality in a variety of metabolic bone conditions. Image acquisition and analysis protocols are well defined for the … Address correspondence to Dr. C.
