灰白质

他们大脑中特定区域的灰白质含量很可能更高。

They are likely to come with larger volumes of white and grey matter in certain areas of the brain .

在MRI图像上，灰白质区的ADC值由计算机辅助分析程序获取。

On MRI images , ADC values were measured in gray-and white-matter regions by using the computer-aided analysis program .

PET扫描发现了脑部一个名为海马状突起（大脑侧面脑室壁上的隆起物，主要由灰白质构成，在泛记过程中起主要作用）的区域活性减弱的现象。

The PET scans detected reduced activity in an area of the brain called the hippocampus , which is known to be damaged in Alzheimer 's.

结果31例迟发性脑内血肿首次CT检查主要异常表现包括：（1）限局性脑实质密度减低，灰白质分界不清18例。

Results The abnormal findings of CT studies of the 31 delayed traumatic brain hematomas included : ( 1 ) Decreased density of the local brain parenchyma and disappeared difference between gray and white matter of the same area in 18 cases ;

结果MRI显示4例为单发，2例为多发，共9个病灶，其中位于大脑半球深部4个，灰白质交界区5个，累及胼胝体2个。

Results On MR images , single lesions were found in 4 cases and multiple ones in 2.Among the 9 lesions of 6 cases , 4 located in deep brain tissue , 5 in white gray matter junction . Corpus callosum infiltration was found in 2 cases .

脑灰白质向内移位。

Cerebral white and gray matter move to inside .

结果单发脑转移瘤病灶多位于大脑灰白质交界区；

Results Most of37 cases located at junctional zone between ectocinerea and alba of cerebrum .

脑灰白质界面内移；

Gray & white matter interface displacement ;

磁共振脑灰白质成像的临床应用及进展

颞叶灰质密度减低，脑沟变窄或消失，灰白质界限不清。

Low density of grey matter of temproral lobe , sulci narrowing or disappearance and unclear grey matter margin .

根据胎龄评估脑回的成熟度、灰白质的分界情况、脑室与脑横径比率和蛛网膜下腔的大小。

Gyrus maturation , gray and white matter differentiation , ventricle-to-brain diameter ratio , and subarachnoid space size were evaluated with respect to gestational age .

T2加权成像，脑白质为较高信号，灰质和髓鞘化区域呈明显的低信号，全组新生儿的灰白质对比均清晰明显；

On T2 weighted image , white matter showed hyperintense , the myelinated region and the cortex presented hypointense . Good signal contrast was seen between the white matter and cerebral cortes in all neonates .

有些好处甚至是可视化的，比如大脑灰白质的密度增加，那里包含了大多数的神经元和突触，而且在学习外语时，大脑的部分区域会变得更加活跃。

Some of these are even visible , such higher density of the gray matter that contains most of your brain 's neurons and synapses , and more activity in certain regions when engaging a second language .

结果完成包含皮肤、颅骨、硬膜、静脉窦、脑灰白质、脑干、小脑、脑室系统、颈椎及颈髓的国人头颈三维有限元模型。

Results The 3D finite element model contains scalp , skull , dura mater , falx cerebri , tentorium , cerebrum ( gray and white matter ), cerebellum , brain stem , cerebral ventricles , cervical vertebra and spinal cord .

本文测定了15例慢性酒精中毒性脑病的局部大脑血流量，其结果是患者大脑左右灰白质及大脑各叶的脑血流量均低于正常对照组，以左额叶、顶叶更为明显。

We measured the regional cerebral blood flow ( rCBF ) of the chronic alcohol poisoning encephalopathy on 15 cases . Compared with normal group , the results showed that rCBF of gray and white matter of left and right hemispheres and each lobe were reduced .

一例行腹腔镜左肾上腺肿瘤切除术，术中见肿块呈灰白色、表面较粗糙，切面呈灰白、灰黄色，质软。

The one was made the left adrenal tumor resection by laparoscopic . We saw that tumor was gray , rough surface , cut surface gray , yellowish gray and soft .
