颅内疾病对导水管脑脊液流量的影响

目的：探讨用磁共振相位对比电影(PC cine)对导水管脑脊液定量测量的临床应用价值。方法：将35例中枢神经系统不同疾病分三组，用PC cine方法进行导水管脑脊液流量测量。结果：在脑血管病组伴白质改变时导水管流量增加；梗阻性脑积水导水管流量减少，流动波形异常；交通性脑积水导水管流量增加，波形圆钝。结论：磁共振PC cine方法测量导水管脑脊液流量简单易行，可为临床提供更多的影像信息。

Correlation of intracranial disorder with CSF flow alterations in the aqueduct

Objective:To study the clinical application value of the aqueductal CSF flow measurement by phase contrast cine magnetic resenance (PC cine MR) sequence.Methods:Thirty five patients with different brain disorders were classified into three groups and their CSF flow of aqueduct was measured by the PC cine MR.Results:The aqueductal CSF flow increased in the brain vascular disease with white matter changes. The aqueductal CSF flow decreased and the abnormal flow wave was found in the cases of obstructive hydrocephalus.On the contrary,the aqueductal CSF flow increased obviously and flow wave was broad in the cases of commuricating hydrocephalus.Conclusion:Measurement of CSF flow of aqueduct by the PC cine MR can provide more imaging informations for the diagnosis.
