Abstract:
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.
