Intravoxel incoherent motion diffusion-weighted MRI (IVIM) plays an important role in detecting and monitoring microstructure. It offers diffusion and perfusion information at the same time without contrast agents. In this work, we demonstrated IVIM parameters can discriminate the microstructure of marrow in younger women from men compared with the apparent diffusion coefficient (ADC) values. It may provide noninvasive methods for evaluating cellularity, vascular volume and blood velocity of bone marrow.
