Using 3-T MR with 32-ch head coil, ultra high resolution DTI and SWI were acquired to evaluate the fine inner structure of the optic radiation and cortico-medullary junction. In the optic radiation, inner layer and outer layer showed the different DTI parameters and such findings meet with the previous findings by the anatomical methods. In the cortico-medullary junction, high-pass filtered phase image showed the most prominent contrast to surrounding tissue.

采用32路头部线圈的3T磁共振成像，获得超高分辨率的DTI和SWI，以评价视神经放射和皮质-髓质交界处的精细内部结构。在光学照射下，内层和外层表现出不同的DTI参数，这一发现与解剖学方法的研究结果相吻合。在皮质-髓质交界处，高通滤波位相图像与周围组织的对比最为明显。
