| 目的 利用区域动脉自旋标记(t-ASL)技术评估正常成人椎动脉(VA)灌注分布并观察VA直径的影响。方法 前瞻性招募228名健康成人,基于t-ASL图像分析VA幕上灌注分布模式,记录双侧VA直径、双侧VA直径差值绝对值,以及每侧VA供应幕上、小脑及幕上+小脑的灌注体积(PV);以Pearson相关分析观察VA直径与PV幕上、PV小脑及PV幕上+小脑的相关性。结果 VA在幕上脑区存在5种灌注分布模式,据此划分5组;组间双侧VA直径差值绝对值差异有统计学意义(P＜0.001)。双侧VA直径平均值、PV幕上、PV小脑及PV幕上+小脑分别为(1.94±0.49)mm、(91.77±49.34)cm3、(74.72±27.68)cm3及(166.49±59.53)cm3。VA直径与PV幕上、PV小脑及PV幕上+小脑呈低-中度正相关(r=0.483、0.179、0.484,P均＜0.001)。结论 t-ASL区域灌注成像可直观显示VA在幕上脑区的多种灌注分布形式;VA直径对灌注分布模式及灌注量均有一定影响。 |

| Objective To explore the perfusion distribution of vertebral arteries (VA) in healthy adults, and to observe the impact of VA diameter on perfusion distribution based on territorial arterial spin labeling (t-ASL) technique. Methods A total of 228 healthy adult volunteers were prospectively recruited. t-ASL imaging was utilized to analyze VA perfusion patterns in supratentorial region. Bilateral VA diameters, absolute inter-side VA diameter differences, as well as perfusion volumes (PV) supplied by each VA to supratentorial, cerebellar and their combined were recorded. Pearson correlation analysis was performed to analyze the correlations of VA diameters with PVsupratentorial, PVcerebellar and PVsupratentorial+cerebellar. Results Five patterns of distinct perfusion distribution were identified in supratentorial region, leading to participant stratification into 5 groups. Significant differences of absolute inter-side VA diameter differences was found among groups (P＜0.001). The mean bilateral VA diameter, PVsupratentorial, PVcerebellar and PVsupratentorial+cerebellar was (1.94±0.49)mm, (91.77±49.34)cm3, (74.72±27.68)cm3 and (166.49±59.53)cm3, respectively. VA diameter showed low-moderate positive correlations with PVsupratentorial, PVcerebellar and PVsupratentorial+cerebellar (r=0.483, 0.179, 0.484, all P＜0.001). Conclusion Perfusion imaging of t-ASL could visualize various perfusion distribution forms of VA in supratentorial region. Diameter of VA had certain impact on both spatial distribution characteristics and quantitative perfusion volumes. |
