目标。本文就脑脊液的正常表现、与脑脊液血流动力学有关的流动物理学以及由于叠加流动效应引起的脑脊液的常见表现和伪影作一综述。结论正常脑脊液具有T1加权序列低信号、T2加权序列高信号的固有特征。然而，正常的脑脊液信号经常被叠加的流动现象改变，这可能会混淆解释。
OBJECTIVE. The purpose of this article is to review the normal appearance of CSF, flow physics in relation to CSF flow dynamics, and commonly encountered appearances and artifacts of CSF due to superimposed flow effects.CONCLUSION. Normal CSF has inherent MRI properties of low signal intensity on T1-weighted sequences and high signal intensity on T2-weighted sequences. However, the normal CSF signal is frequently altered by superimposed flow phenomena that can confound interpretation.
