| 摘 要： | 目的在MRI片上测量国人及Chiari Ⅰ型畸形的颈髓角,并对比分析,探讨其临床意义,为诊断Chiari Ⅰ型畸形提供一个可靠的参考标准。方法选择126例国人成人（18~74岁）正常头颅的MRI片,测量其上颈髓与延髓中心轴线两直线间的夹角,即颈髓角。结果 126例颈髓角最小值156°,最大173.9°,平均166.2°,95%可信区间为159.77°~171.14°;20例Chiari Ⅰ型畸形患者,最大角度为173.2°,最小角度为159.9°,其样本均数95%可信区间为160.25°~172.02°。正常组与病例组该角度大小差异有显著性（P=0.000）。结论对于Chiari Ⅰ型畸形的诊断,MR能够直接显示脑桥延髓受压及小脑下疝的情况,在MRI成像中可以参考以上参考值对于该疾病作出正确的诊断。 |

| Abstract: | Objective: To determine the angle between medulla oblongata and upper spinal cord on midsagittal MRI in normal Chinese individuals and patients with Chiari type 1 malformation to provide a clinical reference and study their clinical significance by MRI.Methods: 126 Chinese with no evidence of CNS abnormity and 20 patients with Chiari type 1 malformation diagnosed by X-ray film were studied by MRI.The measurement was performed on the central sagittal slice.Results: The normal cervico-medullary angle had a mi... |
