Bone Density and Cortical Thickness in Normal, Osteopenic, and Osteoporotic Sacra
Figure 1
Cancellous and cortical regions of interest with cancellous bone density and cortical thickness. (a) Letter outside the sacrum represents the location of cortical measurements on each slice; the inside letters and ovals represent the cancellous regions of interest. (b) Bone mineral density by region of interest for the normal, osteopenic, and osteoporotic groups. (c) Cortical thickness by region of interest for the normal, osteopenic, and osteoporotic groups. * negative values (see Table 2).
