| 目的 应用3.0T磁共振血管成像(MRA)技术探讨后交通动脉开放情况与双侧大脑后动脉及基底动脉形态之间的关系。方法 对108名受试者行MRA及常规MRI。观察双侧大脑后动脉P1段粗细及后交通动脉开放情况,测量基底动脉直线长度及内径,并进行统计学分析。结果 大脑后动脉P1段粗细与其同侧后交通动脉粗细相关(Kendall等级相关,右侧:相关系数rk=0.44,P<0.01;左侧:相关系数rk=0.50,P<0.01)。双侧后交通动脉均未开放者基底动脉长度比单侧或双侧后交通动脉开放者长(P<0.05)。双侧后交通动脉均未开放者基底动脉管腔平均直径比单侧或双侧后交通动脉开放者宽(P<0.01)。结论 大脑后动脉P1段粗细及基底动脉长度、直径与后交通动脉是否开放有关。 |

| Objective To investigate the relationship between the posterior communicating artery (PcoA) and the shape of the posterior cerebral artery and basilar artery with 3.0T magnetic resonance angiography (MRA). Methods A total of 108 subjects underwent MRA and conventional MRI. The diameter of P1 segment of the posterior cerebral artery was recorded. The state of PcoA was observed, and the length and diameter of the basilar artery was measured. Then statistic analysis was performed. Results There was relationship between the diameter of P1 segment of the posterior cerebral artery and PcoA (Kendall rank correlation,right: Correlation coefficient rk=0.44,P<0.01; left: Correlation coefficient rk=0.50,P<0.01). The straight line length of the basilar artery in subjects whose bilateral PCoA undeveloped was longer than those unilateral or bilateral communicating artery developed (P<0.05). The average diameter of the basilar artery in subjects whose bilateral PCoA undeveloped was wider than those unilateral or bilateral communicating artery developed (P<0.01). Conclusion The diameter of P1 segment of the posterior cerebral artery, the length and diameter of the basilar artery associate with whether the PCoA developing or not. |
