We proposed a new technique for the lumbar spine MR bone imaging based on broadband inversion recovery prepared segmented multispoke UTE sequence with k-space weighted navigator gating (3D BoneVIEW) for assessment of low back pain. 3D BoneVIEW provided robust bone imaging with sufficient background suppression and without respiratory artifacts. This sequence has a great potential to help more accurate assessment of the low back pain as an alternative to CT imaging.
