Abstract:
Objective To evaluate the feasibility of the cerebrospinal fluid (CSF) flow measurement by cine phase contrast MRI. Methods Evaluation of intracranial and intraspinal CSF flow was accomplished by the use of periphery gated cine phase contrast MRI technique. Normal patterns of pulsatile flow within the ventricles, cisterns and cervical subarachnoid space were established by this technique. Results CSF flow within ventricle, cistern and subarachnoid space could be clearly displayed, and the relationships between the cardiac cycle and the CSF pulsations were demonstrated on both magnitude reconstruction and phase reconstruction MR images. Conclusions Cine phase contrast MRI is capable of demonstrating intracranial and intraspinal CSF flow. As a new noninvasive technique, it is really superior than other modalities in studying the flow pattern and direction of CSF.
