3.0T MRI对中脑导水管脑脊液动力学研究

Research of 3.0T MRI on Cerebrospinal Fluid Dynamics in the Midbrain Aqueduct

目的应用3.0T磁共振对中脑导水管脑脊液动力学进行初步研究。方法选择2014年9月—2015年9月在该院进行磁共振脑脊液检查的患者共23例,所有患者在常规MRI扫描的基础上进行磁共振脑脊液检查,序列设计包括:3D TSE DRIVE序列、cine PC序列、Q-Flow序列,分别用于观察中脑导水管细节解剖结构、脑脊液流动状态,并绘制时间-信号强度曲线。结果 23例患者进行检查,其中2例正常,3例梗阻性脑积水,16例交通性脑积水,2例脑积水脑室-腹腔分流术后复查脑脊液流动状态未见异常。结论 3D TSE DRIVE序列、cine PC序列和Q-Flow序列相结合能够对中脑导水管区的脑脊液动力学进行全面的观察研究。

Objective To research on cerebrospinal fluid dynamics in the midbrain aqueduct by application of 3.0 T magnetic resonance.Methods From September 2014 and September 2015,selected 23 patients accepted magnetic resonance cerebrospinal fluid examination in our hospital,all patients carried out magnetic resonance cerebrospinal fluid examination on the basis of routine MRI scans,sequence design includes：3 D TSE DRIVE,cine PC sequences,Q-Flow sequence,which were used to observe the midbrain aqueduct detail anatomical structure,cerebrospinal fluid flow state,and drawing the time-signal intensity curve.Results Among 23 patients,including 2 cases were normal,3 cases were obstructive hydrocephalus,16 cases were traffic hydrocephalus,2 cases had not abnormalities by reexamining cerebrospinal fluid flow state postoperative water on the brain ventricle-peritoneal shunt.Conclusion Combination of 3 D TSE DRIVE,cine PC sequences and Q-Flow sequence could have a comprehensive study on the cerebrospinal fluid dynamics in the midbrain aqueduct area.
