The current study aims to assess the feasibility of proton density (PD) in the lumbar using 3D adiabatic inversion recovery prepared ultrashort TE cones (3D IR‐UTE‐Cones) sequence. In addition, the latent associations between the PD and BMD, age, gender, the oswestry disability index (ODI) were evaluated, respectively. It was concluded that proton density of trabecular bone can be applied in lumbar. Moreover, the proton density of lumbar were observed to correlate with BMD, age and ODI, which need further study to clarify this topic.
