使用 T2 加权 MRI，我们测量了 54 名延髓（A 组）、手臂（B 组）和腿部（C 组）肌肉不成比例无力的患者的小放射冠梗塞的相对前后距离。病变位置不同（p<0.01）：A组，大部分位于前方； B组，大部分处于中间；和C组，大多数位于后方。这些结果表明，运动纤维在人体辐射冠中按体位排列。
Using T2-weighted MRI, we measured the relative anteroposterior distance of small corona radiata infarcts in 54 patients who had disproportionate weakness in the bulbar ( Group A), arm ( Group B), and leg ( Group C) muscles. The lesions were differently ( p < 0.01) located: Group A, most were located anteriorly; Group B, most were in the middle; and Group C, most were located posteriorly. These results suggest that motor fibers are somatotopically arranged in the human corona radiata.
