弥散张量纤维束成像在脑膜瘤诊断中的初步应用研究

目的:探讨弥散张量纤维束成像在脑膜瘤诊断中的价值。方法:对11例脑膜瘤(男2例,女9例,年龄范围25～63岁,平均为42.2岁)患者进行弥散张量成像,利用个人计算机对获得的数据进行弥散张量纤维束成像,观察脑膜瘤所引起的白质纤维束的改变情况。结果:颅内占位病变所致白质纤维的异常有三种基本改变形式,分别是破坏、浸润和移位。11例脑膜瘤中有3例引起白质纤维移位加浸润,8例引起白质纤维移位。结论:弥散张量纤维束成像可以显示脑膜瘤与白质纤维束之间的关系,有利于手术方案的制定或病人预后的预测。

Preliminary application study of diffusion tensor tracking in meningioma

Objevtive:To evaluate the value of diffusion tensor tracking in the diagnosis of meningioma.Methods:To study 11 Meningiomas(2 men and 9 women;aged 25 to 63 years;mean age of 42.2 years.)using diffusion tensor tracking.DTT maps were obtained in all 11 patients to observe the abnormality of cerebral white matter induced by meningiomas.Results:The abnormality of cerebral white matter was classified into three types:disruption,infiltration,and displacement.Displacement plus infiltration (3 cases) and displacement (8 cases) were found in 11cases.Conclusion: Diffusion tensor tracking can show the relationship between meningioma and cerebral white matter and is beneficial in the surgical planning or prognosticating the prognosis of patients.
