| 目的 采用磁共振相位对比电影成像技术（PC-MRI）探讨Chiari畸形Ⅰ型伴脊髓空洞症患者枕大池成形术前后脑脊液动力学的变化。方法 选取Chiari畸形Ⅰ型伴脊髓空洞症患者30例，均行枕大池成形术治疗。采用PC-MRI对所有患者术前24 h及术后6个月行脑脊液动力学检测，定量分析其每搏输出量（SV）、平均流量（MF）、反流分数（RF）和最大峰值流速（Vmax）。结果 PC-MRI显示患者术后脑脊液SV、MF增加，双向Vmax减小，与术前比较差异均有统计学意义（P均<0.05），以C2~3椎间盘层面最为明显。结论 PC-MRI可定量分析Chiari畸形手术前后脑脊液动力学变化。 |

| Objective To evaluate the changes of cerebrospinal fluid dynamics of Chiari malformation type Ⅰ associated syringomyelia patients with phase-contrast MRI (PC-MRI). Methods Thirty cases diagnosed with Chiari malformation type Ⅰ associated with syringomyelia clinically underwent cisterna plasty treatment. Cerebrospinal fluid dynamics changes were measured before 24 h and 6 months after operation with PC-MRI. The stroke volume (SV), mean flow (MF), regurgitation fractions (RF) and the maximum peak flow velocity (Vmax) were analyzed. Results After operation, PC-MRI showed SV and MF increased, the bidirectional Vmax decreased, which had statistical difference compared with those of preoperation (all P<0.05), and the C2-3 level was the most obvious. Conclusion PC-MRI can quantitative analysis of preoperative and postoperative changes of cerebrospinal fluid flow and peak velocity. |
