Fig. 6From: Evaluation of bone mineral density in adolescent idiopathic scoliosis using a three-dimensional finite element model: a retrospective studyThe bone densities of ROIs on a bone density slice. Region 1 is the concave side ROI, and region 2 is convex side ROI. A high-density zone on the inner side of the region 1 is the 'high-density zone' of the bone mineral density value.
