128例Chiari畸形患者行MRI矢状位T1WI、T2WI扫描情况。结果 MRI显示128例
中
全部有小脑扁桃体下疝及颅后窝容积减小,合并脊髓空洞96例(75％),颅底凹陷53例(41
％),寰枕融合36例(28%);结合MRI特征行手术治疗,总有效率为92％。结论 MRI能清晰显示后脑及脊髓的解剖结构,为诊断C
hiari畸形的首选检查手段,可结合其特征,采取不同的手术方式。 |

| Objective To elucidate the MRI characteristics of
Chiari malformation and discuss its clinical significances. Methods One hundred and twenty-eight patients with Chiari malformation were examined by preoperativel MRI in sagital T1WI and T2WI retrospectively. Results All of the patients had the cerebella tonsil herniation and volume decrease
of posterior fossa,with syringonyelia in 96 cases (75％),basilar invagination in 5
3 cases (41％),atlanto-occipital fusion in 36 cases (28%).The different operations were performed according to the MRI characteristics,and the operation effect
was satisfactory (92%). Conclusion MRI can show the anatomic
characteristics of the Chiari malformation clearly,so it is the best way to dignose the disease.We can choice different operations according to the MRI chara
cteristics. |
