纤维束

Therefore,when formulating the programme of intracranial tumor resection,it is not only to resect the tumor to the greatest extent,but also to avoid the injury of the important function area in the brain and relevant area of the cerebral white matter,and thus to enhance the quality of patients′ life after surgery.

因此在制定颅内肿瘤切除的方案时，不仅要最大限度切除肿瘤，还要注意术中尽量避免脑的重要功能区及相关白质纤维束的损伤，从而提高患者术后的生活质量。

Within differential geometry are the concepts of fiber bundles and calculus on manifolds , in particular, vector and tensor calculus .

微分几何包含这样的概念：纤维束和流形上的微积分，特别是矢量与张量微积分。

For volunteers, fractional anisotropy were measured in the capsula interna, the corpus callosum and the centrum semiovale.

对正常志愿者分别在内囊、胼胝体以及半卵圃中心选择感兴趣区测量主要白质纤维束FA值。

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。

Can be solid or cystic, have low T2 signal intensity (due to areas composed of interlacing bundles of spindle cells or collagenous septations), which is considered to be a suggestive feature of the diagnosis.

可以是实性或囊性，T2低信号（由于病变由交错的梭形细胞纤维束或胶原分隔组成），这被认为是有助于诊断的特征性改变。

All these cerebral commissural fibers had high intensity in T1 weighted imagings.

这些连合纤维束在MRIT1加权像上信号较高呈灰白色影像。

The morphology and distribution of the eloquent cortex and white matter were evaluated by fMRI before the operation, and the epilepsy focus was localized to guide resections of the tumor and epileptogenic focus by ECoG records during the operation.

术前通过fMRI 了解相应脑功能区皮质和白质纤维束的形态和分布；术中在切除肿瘤前后行ECoG检测，确定致灶的位置，指导肿瘤及致灶的切除。

Helically wound glass fiber strands and the sand-coating process were introduced to bars during the manufacturing to improve their bond to the concrete.

采用拉挤工艺制备了FRP筋，为改进FRP筋与混凝土的粘结性能，在FRP筋表面采用螺旋缠绕纤维束和粘砂。

The interlaminar shear strength of materials is 27MPa, which is enhanced by the fibers vertical to layers.

材料的层间剪切强度为27MPa，垂直无纬布和胎网铺层的纤维束避免了材料的层间开裂现象。

Position: a thick lamina of white matter lying between caudate nucleus, thalamus and lentiform nucleus

掌握基底核的组成、内囊的概念、分部及主要投射纤维束。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
