Abstract
Flow velocity of cerebrospinal fluid (CSF) was analyzed at the aqueduct and the prepontine cistern with a 1.5 tesla superconductive type magnetic resonance imager (Sierra, GE Yokogawa Medical Co.). Cine mode phase contrast MR pulse sequence using periphral gating was used to measure CSF flow direction and velocity. The CSF flow studies were done under the slice thickness of 10mm or 2mm. The flow patterns observed at 2mm thin slice showed distinct to-and-fro-pattern of aqueductal CSF flow and seemed to reflect the peripheral pulse rhythm. Until quite recently such invasive examination as the computed tomographic cisternography has been required to comprehend the CSF dynamics. The presented scan technique of cine mode magnetic resonance image is capable of comprehending the CSF dynamics without any invasive procedure.
