Diffusion weighted Hyperecho Imaging has maintained some interest during the last years since it has the potential to offer a probe for tissue microstructure. The present work studies the influence of idealized rectangular gradient shapes on the quantitation of effective b-factors in diffusion weighted Hyperecho preparation schemes for a variety of MR parameters.
