| 摘 要： | 目的探讨弥散张量成像在脑深部肿瘤白质纤维束弥散特征变化的应用价值。方法20例脑深部肿瘤患者，术前常规行MRI、DTI检查，构建各向异性分数（FA）图和表观弥散系数（ADC）图，测量肿瘤邻近区白质纤维束和其相对应正常脑白质纤维束的FA值、ADC值。结果肿瘤邻近白质纤维束区、相对应正常脑白质纤维束区之间FA、ADC均值的差异有显著统计学意义。结论脑深部肿瘤白质纤维束弥散特征的变化对为深部脑肿瘤的治疗计划提供了重要的信息。

| Abstract: | Objective To explore the value of diffusion tensor imaging (DTI) in the alteration of diffusion characterization in the white matter of deep-seated brain tumor.Methods 20 patients with deep-seated brain tumors were underwent routine MRI examination and DTI,acquired the fractional anisotropy (FA)maps,apparent diffusion coefficients (ADC) maps,The values of apparent diffusion coefficient (ADC) and fractional anisotropy (FA) were measured in the adjacent white matter (WM) to deep-seated brain tumors and the co... |
