摘要：

目的　探讨一般人群生理状态下各种脑血管形态学类型所占比例、性别比等。方法　连续性抽取正常MRA图像计1081份定义为一般人群生理状态下的脑血管形态学类型，按颈内动脉供血范围及Willis环发育情况进行分型，分析各种类型发生情况。结果一侧A1优势型与非一侧A1优势型性别构成无统计学意义 (x2 =1.6274 P=0.2024)，左右侧性别构成无统计学意义 (x2=3.5353 P=0.0601)。左侧A1优势型发生率（121/164）与右侧A1优势型发生率（43/164）存在显著性差异（u＝6.09，P <0.001），左侧发生率明显高于右侧发生率。前循环优势型与非前循环优势型无性别侧别构成差异(x2=0.6285,P =0.4279)，在性别构成上存在显著性差异(x2=30.1706, P<0.001)，前循环优势型更亦发生在女性。一侧A1优势型合并前循环优势与非一侧A1优势型发生前循环优势发生率无统计学意义（x2=0.1254,P =0.7233）。生理状态下标准均衡型MRA完整Willis环显示率较低。结论　MRA是一种无创、有效的评价生理状态脑血管类型的方法，利用MRA评价生理状态下脑血管类型可以为其他与脑血管类型有关疾病提供正常对照。

Abstract:

Objective　To study the proportion and sex ratio of various kinds of cerebral vessels in normal condition.　Method　1081 magnetic resonance angiography(MRA) images performed in recent two years were defined as shape of cerebral vessels in normal condition. According to the blood-supply scope of internal carotid artery (ICA) and developmental condition of Willis circle, we divide and analyze occurrence of various types.　Result　The composition of gender in one-sided dominance and non-one-sided dominance was not statistically significant (x2=1.6274 P=0.2024),The incidence of left A1 dominance (121/164) and right A1 dominance (43/164) showed significant difference (u＝6.09,P<0.001), left dominance showed high incidence obviously. The composition of pro-circulation and non-pro-circulation was not statistically significant in side (x2=0.6285 P=0.4279) and showed significant difference in gender(x2=30.1706 P<0.001), female had higher incidence. In the incidence between the combination of one-sided dominance with pro-circulation and pro-circulation in non-one-sided dominance there was no statisticall significance (x2=0.1254 P=0.7233).In normal condition ,The display ratio of complete Willis circle of MRA was lower.　Conclusion　MRA was an non-invasive and effective method to study the type of cerebral in normal condition, and it can as the control group for other disease related with various types of cerebral vessels.

Key words: MRA, Type of cerebral vessels, Normal condition, Willis circle
