| 目的 观察脑膜瘤与低级别胶质瘤基于小波变换的运动功能网络动态连接的差异。方法 选取脑膜瘤（脑膜瘤组）及低级别胶质瘤（胶质瘤组）患者各14例及正常对照者（对照组）14名，采用小波变换一致性（WTC）方法分析3组运动功能网络动态连接情况。结果 基于双手运动任务刺激及广义线性模型分析确定3组运动功能网络节点分别为左右侧主要运动皮层激活区（LPMC、RPMC）及辅助运动皮层激活区（SMA）。在运动网络LPMC、RPMC、SMA感兴趣区（ROI）内，脑膜瘤组、胶质瘤组LPMC-SMA、RPMC-SMA、LPMC-RPMC的WTC均低于对照组（P均<0.05），胶质瘤组均低于脑膜瘤组（P均<0.05）。结论 利用WTC方法能够敏感观察脑膜瘤与低级别胶质瘤运动功能网络连接的低频振荡改变。 |

| Objective To observe the differences of dynamic connectivity in motor function networks between meningioma and low-grade glioma. Methods Totally 14 patients with meningioma (meningioma group), 14 patients with low grade gliomas (gliomas group) and 14 healthy controls (control group) were enrolled. The wavelet transform coherence (WTC) was used to analyze the dynamic connectivity in motor function networks of 3 groups. Results The motor function networks nodes were determined by hands movement task stimulus and the generalized linear model analysis, which located at the left and right side of the primary motor cortex (LPMC and RPMC) and the supplementary motor area (SMA). The values of WTC in LPMC-SMA, RPMC-SMA and LPMC-RPMC in meningioma group and gliomas group were lower than those in control group, and in gliomas group were lower than those in meningioma group (all P<0.05). Conclusion Low frequency fluctuation alteration of connectivity in motor function networks in patients with meningioma and low grade gliomas can be sensitively detected using WTC. |
