A CAT scan was recorded from 123 patients with left hemisphere damage from stroke. They were divided into four groups according to presence or absence of ideomotor apraxia and length of illness (15 to 90 days and over 90 days). The lesions were mapped and compared in the four experimental groups for anteroposterior dimension, lesion depth--deep-seated lesions deing separated from lesions with a superficial component--and position with respect to the Sylvian fissure for lesions encroaching on the surface. In the anteroposterior dimension there is no material difference in the distribution of the lesions with respect to length of illness. Moreover, any difference is hardly detectable between the profiles for patients with and without ideomotor apraxia except for the higher frequency of deep lesions in the non-apraxic group. The same holds true for "small" lesions.
对123名因中风导致左半球损伤的患者进行了计算机断层扫描（CAT扫描）。根据观念运动性失用症的有无以及病程长短（15至90天和超过90天）将他们分为四组。对四个实验组的病变进行了映射，并比较了其前后尺寸、病变深度（深部病变与具有浅表成分的病变区分开来）以及对于侵犯表面的病变而言相对于外侧裂的位置。在前后尺寸方面，病变分布在病程长短上没有实质性差异。此外，除了非失用症组深部病变的频率较高外，有观念运动性失用症和无观念运动性失用症患者的病变情况几乎没有差异。“小”病变也是如此。
