目的：探讨正常成人体检行三维时间飞跃法(3D-TOF)磁共振血管造影(MRA)检查时大脑动脉环(Willis环)变异情况及其临床意义。方法：回顾性分析接受体检3D-TOF MRA检查的442名正常成人体检者的MRA图像，运用后处理软件分析其血管形态特点。结果：442名体检者中，发现152例Willis环变异者，其中大脑前动脉(ACA)A1段的缺如占10.53%(16/152)，A1段发育不良占36.18%(55/152)，A1段开窗占3.29%(5/152)，A1段的发育不良或缺如与同侧PCoA增粗呈正相关；A2段变异占15.13%(23/152)；ACoA段变异者占4.61%(7/152)；PCoA段增粗占66.45%(101/152)，且女性大于男性；P1段变异占44.74%(68/152)。结论：体检3D-TOF MRA检查可清晰显示正常成人Willis环的变异，为临床相关疾病提供指导价值。
目的：探討正常成人體檢行三維時間飛躍法(3D-TOF)磁共振血管造影(MRA)檢查時大腦動脈環(Willis環)變異情況及其臨床意義。方法：迴顧性分析接受體檢3D-TOF MRA檢查的442名正常成人體檢者的MRA圖像，運用後處理軟件分析其血管形態特點。結果：442名體檢者中，髮現152例Willis環變異者，其中大腦前動脈(ACA)A1段的缺如佔10.53%(16/152)，A1段髮育不良佔36.18%(55/152)，A1段開窗佔3.29%(5/152)，A1段的髮育不良或缺如與同側PCoA增粗呈正相關；A2段變異佔15.13%(23/152)；ACoA段變異者佔4.61%(7/152)；PCoA段增粗佔66.45%(101/152)，且女性大于男性；P1段變異佔44.74%(68/152)。結論：體檢3D-TOF MRA檢查可清晰顯示正常成人Willis環的變異，為臨床相關疾病提供指導價值。

Objective:To investigate morphologic variations of circle of Willis in healthy adults using 3D-TOF MR angiography in medical examination and its clinical significance. Methods:To analyze the characteristics of the vascular morphology in 442 healthy adults of head 3D-TOF MRA in the post processing workstation retrospectively. Results: All the 442 cases, the variations of circle of Willis were found in 152,the variations of A1, A2, ACoA, PCoA, P1 were found in 76(50.00%), 23(15.13%), 7(4.61%), 101(66.45%), 68(44.74%). The variation of A1 was positively correlated with PCoA, the variation of PCoA in female was more than in male. Conclusion:Medical examination-3D-TOF MRA has important value to display morphologic variations of circle of Willis in healthy adults, which can provide important guide value in the clinical.
