脊髓空洞症的MRI诊断

DIAGNOSIS OF SYRINGOMYELIA WITH MRI

①目的 评价ＭＲＩ对脊髓空洞症的诊断价值。②方法 采用ＳＥ序列Ｔ１，Ｔ２ 加权像及质子像，对３８例脊髓空洞症病人进行多种体位扫描。③结果 ＭＲＩ扫描能清楚显示小脑扁桃体下降的程度，脊髓空洞的范围、形态及脊髓外形的改变。④结论 ＭＲＩ是诊断脊髓空洞症的有效方法。

Objective\ To evaluate the value of MRI in the diagnosis of syringomyelia.\ Methods\ 38 patients with syringomyelia were examined by spin echo(SE) sequence on coronal, saggital, axial planes and T 1WI, T 2WI, proton imaging. Results\ The descending degree of cerebellar tonsil, the extent and shape of the cavity, and the appearance of spine cord were clearly shown by MR imaging.\ Conclusion\ MR imaging is an effective method in the diagnosis of syringomyelia.\;
