Abstract: Methods and systems for performing magnetic resonance diffusion weighted imaging of an object is provided. The method includes applying a plurality of diffusion gradients to a plurality of image slices of the object during a plurality of repetition times via an MRI system. A different diffusion gradient of the plurality is applied to each image slice during the same repetition time.
