MRI has become preferred over other imaging modalities in evaluating marrow compositions. Although the routine MRI can evaluate the cellularity of marrow according to signal intensity, it’s not quantitative analysis. IVIM provides both diffusion and perfusion quantification using a single imaging study at the same time, without intravenous contrast injection. IVIM has been applied in various diseases, but the application of IVIM in marrow composition is less. As the preliminary study, we will adopt the parameters of IVIM to assess the vertebral bone marrow microstructure, then to investigate gender-related cellular and capillary network of vertebral marrow in healthy young adults.
