目的：探讨Chiari畸形的低场MRI表现，评价低场MRI对Chiari畸形的诊断价值。方法回顾性分析封丘县人民医院诊断为Chiari畸形的18例患者的MRI 影像学资料及临床资料。结果小脑扁桃体下疝至枕大孔平面下5~19 mm，其中伴脊髓空洞症11例，伴脑积水5例，二者并存1例，合并颅底凹陷症1例。结论低场MRI可清晰显示后颅凹、脊髓的解剖结构，并可显示颅底及其他发育异常，是Chiari畸形的最佳影像学诊断方法，对其临床治疗及预后判断具有重要参考价值。

Objective To investigate the performance of low field MRI in Chiari malformation,and evaluate the diagnostic val-ue of low field MRI in Chiari malformation. Methods The clinical data of 18 patients who were diagnosed with Chiari malformation were retrospectively analyzed. Results The cerebellar tonsillar hernia to magnum 5-19 mm,of which 11 cases associated with sy-ringomyelia,5 cases with hydrocephalus,1 case with both of the above,1 case was complicated with basilar invagination. Conclu-sion The low field MRI can clearly show the anatomy of posterior fossa,spinal cord,and can display the skull base and other de-velopmental abnormalities,is the best method for diagnosis of Chiari malformation,has important reference value for the clinical treatment and prognosis.
