Materials and Methods: Six patients with left frontal lobe tumors (4 gliomas, 1 germinoma, 1 intra-axial cavernoma) close to Brocca and Wernicke language areas were studied. BOLD and DTI were performed on a 3.0T magnet GE Signa Excite~(? HD_X, BOLD using the word association paradigm developed in Part I and DTT technique developed in PartII. Language activation maps and fiber tracts were superimposed upon high resolution T1 weighted anatomic images of the brain for displaying the relationship between tumor, language functional areas and white matter tracts.

材料和方法：使用GE 3.0 T Singa Excite~ HD_x超导磁共振成像系统，对6例左侧语言相关脑区肿瘤(Ⅲ-Ⅳ级胶质瘤1例，Ⅱ级胶质瘤3例，生殖细胞瘤1例，海绵状血管瘤1例)行BOLD-fMRI及扩散张量成像扫描，BOLD应用语义相关判断作为任务刺激，所有数据进行离线后处理，应用AFNI软件处理BOLD图像，观察语言功能皮层的激活；DTT采用日本东京大学的Volume-one1.56和diffusion TENSOR Visualizer 1.5进行纤维束成像处理。
