Bone water occurs at various locations and in different binding states, including water bound to organic matrix and free water residing in the microscopic pores of cortical bone. Cortical bone is typically regarded as MR invisible with conventional clinical MR sequences. In this study, we aimed to investigate bone water imaging with UTE and clinical FSE sequences, and to correlate the structure seen with FSE imaging with that seen with uCT imaging.
