In this study we propose using a MR elastography reconstruction method adjust the ratio between wavelength and spatial resolution, by resampling the matrix of shear displacement locally, to optimize the quality of the reconstruction. This reconstruction algorithm was compared to existing direct inversion algorithms in phantoms, healthy volunteers and patients with liver fibrosis. We observed that the algorithm k-MDEV showing the best performance in phantoms and patients did not have the best repeatability. Our proposed method improved the diagnostic performance for advanced fibrosis, compared to classical direct inversion method, without a negative effect on repeatability.
