Research Abstract

Cardiac-gated cerebrospinal fluid space MR imaging was applied on 3T MR machine. High-contrast and high-resolution cardiac-gated cerebrospinal fluid space MR images were obtained with the combination use of a high-field 3T MR machine and a multi-channel head coil. We found that the brain tissue volume change related to cardiac pulsation was relatively small, and analysis of the volumetric and morphological analysis was difficult. Further technical improvement is tried for the future clinical analysis.
