Systems and methods for cell size imaging using MRI systems are provided. An exemplary method includes obtaining first diffusion MRI data for biological tissues of interest and at least one second diffusion MRI data for the biological tissues of interest having a different diffusion time than the first diffusion MRI data. The method also includes calculating, from the first and at least one second diffusion MRI data, incremental area under curve values of the first and at least one second diffusion MRI data for a chosen diffusion time range. Thereafter, an image for the biological tissues of interest is generated, wherein intensity values for each of the plurality of image voxels is based on a corresponding one of the incremental area under curve values.
