16 patients with hydrocephalus communicans and 5 healthy volunteers were examined to demonstrate the pattern of the pulsatile CSF flow. After implantation of a CSF shunt system the same patients were examined again to show the influence of the shunt on the CSF pulsations. We used a flow-sensitised, cardiac-gated 2D FLASH sequence and analysed the phase and magnitude images. It could be shown that most patients (n = 12) had a hyperdynamic pulsatile flow preoperatively. After shunt implantation the pulsatile CSF motion and the clinical symptoms were improved in 8 of these patients. MRI of pulsatile CSF flow movement seems to be a helpful noninvasive tool to estimate the prognosis of a shunt implantation in patients with hydrocephalus communicans.
对16例交通性脑积水患者和5名健康志愿者进行检查，以显示搏动性脑脊液流动模式。在植入脑脊液分流系统后，再次对同一批患者进行检查，以显示分流对脑脊液搏动的影响。我们使用了流动敏感、心脏门控的二维快速扰相梯度回波序列，并分析了相位和幅度图像。结果表明，大多数患者（n = 12）术前有高动力搏动性血流。在植入分流器后，其中8例患者的搏动性脑脊液运动和临床症状得到改善。搏动性脑脊液流动运动的MRI似乎是一种有助于评估交通性脑积水患者分流植入预后的无创工具。
