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.
