Abstract:
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.
