A computed tomographic method for analyzing the shrinkage of the basis pedunculi (BP) due to the secondary degeneration of the descending fibers was applied in correlation to the site of cerebral lesions in 89 chronic hemiplegic patients. Cerebral lesions in the anterior corona radiata or the anterior limb of the capsula interna caused shrinkage of the medial BP. Lesions in the central corona radiata or the genu and posterior limb of the capsula interna caused shrinkage of the central BP, while lesions of the posterior corona radiata or the posterior limb of the capsula interna caused shrinkage of the lateral BP. These results suggested that CT images are able to reveal the principle sites of atrophy of the descending fiber tracts in chronic hemiplegia.
一种用于分析由于下行纤维继发变性导致的大脑脚（BP）萎缩的计算机断层扫描方法，被应用于89例慢性偏瘫患者，并与脑损伤部位相关联。放射冠前部或内囊前肢的脑损伤导致内侧大脑脚萎缩。放射冠中部或内囊膝部及后肢的损伤导致中央大脑脚萎缩，而放射冠后部或内囊后肢的损伤导致外侧大脑脚萎缩。这些结果表明，CT图像能够揭示慢性偏瘫中下行纤维束萎缩的主要部位。
