The complicated structure of many neuronal regions places an ever-increasing demand on the imaging resolution. By combining 3D encoding with multiecho acquisition on a localized region of interest, the current work targets diffusion tensor imaging with 0.8 x 0.8 x 1 mm3 resolution. Penalized iterative reconstruction is also proposed for minimizing the effects of imperfect realization of localized imaging. In vivo results are shown on the human pons.
