A fast MR sequence based on the RARE-myelographic technique allows the determination of cerebrospinal fluid (CSF) flow with a flow sensitivity below 1 mm/sec. The method averages flow over the ECG cycle and consequently measures net flow rather than ECG-dependent flow variations. The noninvasivity of this technique and the very short acquisition time of about 5 sec make this sequence a very useful diagnostic tool for a variety of CSF-flow dependent disorders like the determination of different types of hydrocephalus, the control of shunt operations and the assessment of communication pathways between CSF and cysts.
一种基于RARE脊髓造影技术的快速磁共振序列能够测定脑脊液（CSF）流量，其流量敏感度低于1毫米/秒。该方法对心电图周期内的流量进行平均，因此测量的是净流量，而非依赖心电图的流量变化。此技术的非侵入性以及约5秒的极短采集时间，使其成为诊断多种脑脊液流量相关疾病的非常有用的工具，如不同类型脑积水的测定、分流手术的监测以及脑脊液与囊肿之间连通路径的评估。
