Previous studies have emphasized that the meniscis complex alignment of collagen fibers contributes to the execution of this function. The purpose of this study is to design a 2D multi-slice dual echo radial sequence with a minimal phase excitation pulse for facilitating visualization of the fiber orientation in human meniscus based on quantitative T2* mapping. Our findings demonstrate that the proposed method allows enhanced visualization of structural details of the human meniscus, and which contributes to derive the spatial T2* distribution and fiber orientation for diagnosing early degenerative changes.
