A total of 50 healthy volunteers aged between 18 and 54 years underwent phase-contrast cine MRI to assess cerebrospinal fluid flow characteristics in different regions of the vertebral canal. The results revealed that the cerebrospinal fluid peak flow velocity and peak flow rate in the systolic phase were significantly greater than those in the diastolic phase at the same level in the subarachnoid space of the cervical spinal canal. The ventral peak flow velocity and peak flow rate were significantly greater than the post-lateral peak flow velocity and flow rate, while there were no differences between left and right post-lateral subarachnoid peak velocity and flow rate. Moreover, there were no significant differences in peak flow velocity and peak flow rate between the systolic and diastolic phases, ventral, right post-lateral or left post-lateral peak flow velocity and peak flow rate at the same level in the subarachnoid space of the cervical spinal canal among different age groups (18-24, 25-34, 35-44, ≥ 45 years).
共有50名年龄在18至54岁之间的健康志愿者接受了相位对比电影磁共振成像检查，以评估椎管不同区域的脑脊液流动特征。结果显示，在颈段椎管蛛网膜下腔的同一水平，收缩期脑脊液的峰值流速和峰值流量显著高于舒张期。腹侧峰值流速和峰值流量显著高于后外侧峰值流速和流量，而后外侧蛛网膜下腔左右峰值流速和流量之间没有差异。此外，不同年龄组（18 - 24岁、25 - 34岁、35 - 44岁、≥45岁）在颈段椎管蛛网膜下腔同一水平的收缩期与舒张期、腹侧、右侧后外侧或左侧后外侧峰值流速和峰值流量之间均无显著差异。
