Many musculoskeletal tissues such as cortical bone have very short transverse relaxation times and require specialized pulse sequences such as UTE or ZTE for optimal signal acquisition. Recently, these sequences have been used to directly visualize cortical bone by suppressing surrounding long T2 tissues such as fat or muscle by either magnetization preparation using inversion recovery, or logarithmic tissue segmentation. In this work, we compare these techniques on a cadaveric bovine knee specimen. Both inversion recovery UTE as well as tissue segmented ZTE imaging proved promising method for direct bone imaging with CT-like image appearance.
