The Application of Advanced Bone Imaging Technologies in Sports Medicine

Figure 1

Comparison of bone microstructural images in the same subject between HR-pQCT (top) and high-resolution MRI (bottom) in the distal tibia and radius. The HR-pQCT scan was taken at 82 μm isotropic voxel size using standard protocols. The high-resolution MRI scan was performed using a previously described protocol with in-plane resolution of 137 μm [16, 24]. The images to the left display the raw images taken which include the background soft tissue and the images to the right show the images segmented and the MRI scan processed such that the signal intensity is inverted. It is clear that, although the modalities have different contrast, both produce similar information about bone microarchitecture.
