Procedure for bone density mapping and measurement. a Mapping bone density from CT. b Slicing a vertebra and aligning ROIs on the concave (labeled “1”) and convex (labeled “2”) sides to calculate mean densities. c Visualizing ROIs on vertebral slices in the entire spine to ensure that their concave and convex labels are consistent. CT: computed tomography; ROI: region of interest
