　　目的：探讨3D平衡全稳态快速场梯度回波（3D Balanced Fast Field Echo以下简称3D B-FFE）序列在脑积水成像中的临床应用价值。材料与方法：采用飞利浦Achieva1.5T双梯度超导型磁共振设备对50例脑室系统有积水的患者进行3D B-FFE序列脑室系统成像扫描。比较该方法与常规T1WI、T2WI显示中脑导水管和室间孔形态的效果。结果：50例患者3D B-FFE序列图像均清晰显示脑室系统，对中脑导水管和室间孔的扩张、狭窄、梗阻的程度和形态与常规SE序列T1WI、T2WI显示效果相比较，3D B-FFE序列有明显优越性。结论：3D B-FFE序列脑室成像扫描能清晰显示脑室积水情况，为临床确诊和治疗提供可靠的依据，可作为一种MR脑室积水成像的新方法。

Objective:To study the clinical value of 3D Balanced Fast Field Echo sequence in MRI examination of encephaledema initially. Methods:Using the PHILIPS Achieva 1.5T double gradients superconduction MRI system, 3D Balanced Fast Field Echo sequence was performed in 50 cases with hydrocephalus. Compared this method with routine T1WI、T2WI to show the advantage on showing aqueduct of midbrain and interventricular foramen. Result:All cases showed the ventricle system clearly by 3D 3D Balanced Fast Field Echo series, which was more advanced than routine T1WI、T2WI on showing the enlarged、stenosed and obstructed midbrain, nterventricular foramen and the aqueduct. Conclusion: 3D Balanced FFE sequence can clearly showed the situation of encephaledema, providing the accordance for clinical diagnosis and therapy, and be a new MRI examination way of encephaledema.
