本文应用磁共振成象技术,测量了100侧正常人的脑干脊髓角。结果表明,正常人的脑干脊髓角平均为163.9度。脑干脊髓角的变化与性别和年龄无直接关系。大部分枕大孔区发育异常病人脑干脊髓角变小。
In this paper, magnetic resonance imaging technique was used to measure the brainstem spinal cord angle of 100 normal subjects. The results showed that the average brain stem spinal cord angle of 163.9 degrees. The change of brainstem spinal cord angle has no direct relation with sex and age. Most of the macroporous dysplasia of patients with brainstem spinal cord angle smaller.
