Figure 1a:

Axial flat-panel volume CT images of distal radius in (a) control subject and (b) woman with AN. Masks (green) created by segmenting out the cortical and trabecular bone structure with a thresholding technique are overlaid on the flat-panel volume CT images. Corresponding three-dimensional models for (c) control subject and (d) woman with AN were created with software (MIMICS) by compiling the masks of 5-mm sectional flat-panel volume CT images. Flat-panel volume CT images and three-dimensional models clearly demonstrate rarefaction of trabeculae and thinning of the cortical shell of the distal radius in AN compared with that in control subject.
