脑白质

Recurrent lesions in the cortex and subcortical white matter of temporal, parietal, and occipital lobe on MRI might provide clues for diagnosis of MELAS syndrome. DWI might show lesions earlier than T2WI in MELAS syndrome similar to cerebral infarction.

MRI反复颞顶枕叶皮质及皮质下白质病灶可为临床诊断提供帮助，与在脑梗死诊断中的作用类似，弥散加权成像可能会更早地显示病灶。

Cranial MRI showed round foci of signal change of different sizes in the subcortical white matter of the cerebral hemisphere, in the left paramedian portion of the pons and near the fourth ventricle.

脑部MRI见大脑半球皮质下白质的不同部位、左侧脑桥旁正中结构靠近第四脑室处散在许多圆形异常信号病灶。

High signal was also seen in the corticospinal tract on T2-weighted images in two of the eight normal volunteers and four of the 16 disease controls: two each with AMN and leukoencephalopathy presenting spastic paraparesis.

在8例正常人对照者中有2例、16例其他神经疾病患者中有4例（2例肾上腺脊髓神经病患者、2例表现为下肢痉挛性轻瘫的不明原因的白质脑病患者）于T2像也可见皮质脊髓束走行区高信号。

Objective To investigate the pathological characteristics of heroin spongiform leukoencephalopathy.

目的 了解海洛因海绵状白质脑病的病理特征。

Objective To elucidate the imaging characteristics of spongiform leukoencephalopathy induced by heroin and the diagnostic value of MRI and CT examinations.

目的 阐述吸食海洛因所致海绵状白质脑病的影像学表现及CT、MR的诊断价值。

To investigate the expression and significance of apoptosis and its relation with the expression of Caspase-3 protein in heroin spongiform leukoencephalopathy patients.

目的 探讨海洛因海绵状白质脑病胶质细胞凋亡及其Caspase-3蛋白的表达。

Objective To study the characteristics and the diagnostic value of CT and MRI imaging in spongiform leukoencephalopathy after inhaling heroin vapor.

目的 研究CT及MRI对因吸食海洛因引起海绵状白质脑病的特征性影像学诊断价值。

But the study also had several limitations. They note that although interreader reliabilities of white-matter and ventricular grades are good, estimates of sulcal grade tend to have greater interreader variability. The researchers also point out that the observed associations could be related to other differences related to fish consumption, such as a healthier lifestyle in general.

不过，此研究也有一些限制；他们指出，虽然不同判读者之间对於白质和心室等级的的信赖度不错，但脑回等级的评估在不同判读者之间有比较大的差异；研究者也指出，观察到的关联可能也与食用鱼类以外的不同状况有关，例如较健康的生活型态。

The dynamic changes of endothelin-1 in cerebrospinal fluid , brain tissues and plasma and ET〓-RNA expression in hypothalamus, hippocampus and temporoparietal grey and white matters were observed by radioimmunoassay methods and spot hybridization respectively.

四、建立双后肢高速、低速投射物致伤犬应激模型，应用核酸斑点杂交和放射免疫分析法，检测分析致伤前及致伤后10min、1h、2h、6h、8h，对犬的脑组织、血浆、脑脊液中的ET〓（内皮素-1）含量及海马、丘脑下部、颞顶叶灰、白质中ET〓-RNA表达的动态。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
