目的: 探讨磁共振水成像技术对脊柱疾病诊断的应用价值。方法: 采用快速高级自旋回波( FASE) 、重T2WI 及脂肪抑制序列对300 例病人检查行磁共振椎管水成像(MR myelography, MRM) 。结果: MRM 显示正常25 例, MRM 异常275 例, 清楚显示原发病变与邻近脊髓腔、脊髓、神经根的相关关系。结论: MRM 具有无创伤、无辐射、速度快, 不需对比剂, 患者易接受的特点。 MRM 与常规MRI 图像结合可获得全面、客观的病变信息, MRM 图像可取代X 线脊髓造影和CT 脊髓造影。

英文摘要:

Objective: To investigate the clinical evaluation of Magnetic Resonance Hydrography(MRH) in the diagnosis of spinal column diseases( SCD) . Methods: MRH was used to detect 300 patients with SCD proved or suspected by using Fast Advanced Spin Echo ( FASE) , heavily T2 weighted image( T2WI) and fat- suppression. Results: MRH showed that the normal was 25 and the abnormal was 275 with correlativity between primary affection and close canals of spinal cord, spinal cord and nerve root. Conclusion: MRH has characteristics of fast speed as well as no injuring, no radiation and no contrast agent; furthermore, which is easy to be accepted by patients with SCD. Combined with routine MRI, MRH can acquire overall and objective information of pathological changes, which can take the place of X- ray myelography and CT mye-l ography.
