基本原理和目标：本研究的目的是阐明的位置和数量的脊髓脑脊液脉动，并区分和量化的心脏和呼吸influence.Materials和方法：回波平面成像序列应用于5个不同水平的7名健康志愿者的椎管。最大流量和呼吸信号的变化量分别由时域和频域analysis.Results：脑脊液脉动高，在颈椎前路和胸腰椎。Cl时呼吸影响增加19%，T12时增加28%。收缩期流量升高，在呼气后期和舒张期向上运动是明显的早期expiration.Conclusion：在较低的脊柱的脉动似乎与CSF运动的第二电机，因为有一个上升的呼吸影响和再现的脉动波。生理性脊髓CSF脉动包含相关的呼吸成分。
Rationale and Objectives: The aim of the study is to elucidate the location and amount of spinal cerebrospinal fluid pulsations and to differentiate and quantify the cardiac and the respiratory influence.Materials and Methods: An echo planar imaging sequence was applied to 5 different levels of the spinal canal of 7 healthy volunteers. The amount of maximal flow and respiratory signal variation were determined by a time and frequency domain analysis, respectively.Results: CSF pulsation was high in the anterior cervical and in the thoracolumbar spine. Respiratory influence rose by 19% at Cl and by 28% at T12. The systolic flow was elevated during late expiration and the diastolic upward movement was pronounced by early expiration.Conclusion: The pulsation in the lower spine seems to be related to a second motor of CSF movement because there is a rising respiratory influence and a reappearance of pulsation waves. Physiological spinal CSF pulsation contains a relevant respiratory component.
