Diffusion weighted imaging is widely used in musculoskeletal MR imaging. Current implementations of diffusion-weighted imaging include the use of PROPELLER DUO imaging sequence and multi-spectral MRI imaging techniques. However, these implementations are restricted by long acquisition times. In this work we propose to an approach to undersample the blades in a uniform fashion and denoise the reconstructed image using total variation based denoising approach. This approach provides acceptable results up to an acceleration factor of 3 and reduces the scan time. This reduction in scan time can be used to acquire multiple slices within clinically feasible scan times.
