本文目的是分析脊髓空洞症ＭＲ表现，探讨空洞内脑脊液博动机理及意义。所用材料和方法是以２９例脊髓空洞症均行ＭＲ矢状位Ｔ１、Ｔ２加权扫描，部分行轴位扫描，观察空洞的长度与脑脊液博动的关系。结果得到２９例空洞累及长度在２～１５个椎体节段，前后径２～１２ｍｍ之间。２２例有脑脊液博动者空洞长度平均累及９个椎体节段，７例无脑脊液博动者平均累及５个椎体节段。结论是ＭＲ对脊髓空洞症的诊断具独到之处，脑脊液的博动与空洞的长度有关，而与宽度无关。空洞内脑脊液博动还可作为观察术后疗效的一项指标。
The purpose of this paper is to analyze MR manifestations of syringomyelia and explore the mechanism and significance of intracranial cerebrospinal fluid movement. Materials and methods used were 29 cases of syringomyelia MR MR sagittal T1, T2 weighted scan, axial scan some of the row, the relationship between the length of the cavity and cerebrospinal fluid dynamics. RESULTS: Twenty-nine cases of obliteration involving 2-15 vertebral segments with a diameter between 2 and 12 mm were obtained. In 22 patients with cerebrospinal fluid (CSF), the average length of the holes involved 9 vertebral segments, and 7 non-cerebrospinal fluid creatures involved 5 vertebral segments. The conclusion is MR MR diagnosis of syringomyelia unique, cerebrospinal fluid movement and the length of the hole, but has nothing to do with the width. Hollow cerebrospinal fluid movement can also be used as an indicator of postoperative efficacy.
