Using the multi-echo ¹H-MRS and multi-echo Dixon VIBE, we measured the proton density fat fraction (PDFF) using MR imaging in the bone marrow of L2-L4 vertebra, and compared with the bone mineral density (BMD) measured using computed tomography (CT). The resutls showed a significant correlation between PDFF measured using the two methods, and also PDFF with BMD.
