Development and clinical application of cardiac-gated cerebrospinal space MR imaging for central nervous system diseases

在3T磁共振机上进行心门脑脊液空间磁共振成像。采用高场3T磁共振机和多通道磁头线圈相结合的方法，获得高对比度、高分辨率的心门脑脊液空间MR图像。我们发现，与心脏搏动相关的脑组织体积变化相对较小，体积分析和形态分析都很困难。并尝试进一步的技术改进，为今后的临床分析做好准备。

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.
