Glucocorticoid-Induced Bone Loss Is Associated with Abnormal Intravertebral Areal Bone Mineral Density Distribution

Figure 1

DXA-derived vertebral subregions defined using Hologic software. ROI 1 (whole) was defined by the four corners of the vertebra. ROIs 2–4 (posterior, middle, and anterior) formed equal thirds in the area of ROI 1, oriented sagittally. ROIs 5–7 (superior, central, and inferior) formed equal thirds in area of ROI 1, oriented transversely. Reprinted from Briggs et al. [42] with permission from Elsevier Copyright Clearance Center.
