Postmenopausal women with osteopenia have higher cortical porosity and thinner cortices at the distal radius and tibia than women with normal aBMD: An in vivo HR‐pQCT study

Increases in cortical porosity (Ct.Po) and decreases in cortical thickness (Ct.Th) are associated with increased bone fragility. The purpose of this study was to validate an autosegmentation method for high-resolution peripheral quantitative computed tomography (HR-pQCT) scans to measure Ct.Po and Ct.Th and use it to compare Ct.Po and Ct.Th between pre- and postmenopausal women with normal, osteopenic, and osteoporotic areal bone mineral density...
