Figure 1

Regions of interest (ROIs) in the proximal tibia for evaluating bone mineral density. ROI of the medial tibial plateau (R1): center of the medial tibial plateau 10 mm distal to the subchondral bone on the anterior–posterior scout image. ROI of the lateral tibial plateau (R2): the center of the lateral tibial plateau, 10 mm distal to the subchondral bone on the anterior–posterior scout image. ROI of the metaphysis (R3): the center of the tibia, 50 mm distal to the joint line of the proximal tibia.
