CT and MR imaging are often both performed in patients with vertebral fractures or degenerative changes, with CT aiming at the characterization of osseous changes and the MR focusing on bone marrow edema. CT is associated with radiation exposure and therefore it is desirable to assess both soft-tissue and osseous components in one MR examination. The present work develops a methodology for simultaneously extracting susceptibility weighted imaging (SWI) and single point Dixon imaging based on a single-TE ultrashort echo time (UTE) scan to simultaneously assess vertebral fractures and degenerative bone changes in the thoracolumbar spine with a single MR sequence.
