磁共振水成像对脊柱疾病诊断中的应用价值

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(MRmyelography,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。

Evaluation of Magnetic Resonance Hydrography in the diagnosis of Spinal Column Diseases

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 myelography.
