查询词典 corpus callosum

objective to study mri diagnostic value on multiple sclerosis.methods mri examination data of 31 patients with multiple sclerosis were analysised retrospectively.results total 184 lesions were detectived in 31 patients.most lesions were located on white watter area beside the lateral ventricle,and a few lesions were located on the spinal cord,cerebellum,brain stem and corpus callosum.the shape of lesion can be circle or ellipse.the lesion showed as slightly long t1 and long t2 signal.the acute stage lesions can have enhancement.conclusions ms have characteristic findings on mri image.mri can show the patholoic changes,and provide strong evidence for clinic diagnosis of multiple sclerosis.

摘 要］目的：探讨多发性硬化（muliplle sclerosis，ms）的mri特征表现及其诊断价值。方法：回顾分析31例临床诊断为ms患者的mri检查资料。结果：31例共发现病灶184个，病灶于侧脑室旁白质区、半卵圆中心及皮层下区最多见，其次见于脊髓小脑、脑干及胼胝体，部分可见视神经受累，病灶呈卵圆形或圆形稍长t1、长t2信号，矢状位像见病灶与侧脑室垂直，急性病灶增强扫描有的可呈结节状、环状或斑点状强化。结论：在mri图像上ms有特征性表现，mri能反应ms病理变化，为临床诊断ms提供可靠依据。

Specifically when operating Go/No go tasks,the brain blood flow in the areas of anterior cingulated cortex,the medial prefrontal,lateral inferior frontal gyrus and corpus callosum rise dramatically,which implies that deficiency may exist in the functions of these parts of the brain,and depressed patients among college students have the problem of behavioral inhibition in the cognitive aspect, which is connected with certain parts of the brain mechanism.

更多数图谱数据分析方法，发现抑郁症组和正常组间存在相应脑区局部脑血流的显著变化，具体体现在执行Go/No go任务时，前扣带回和前额内侧、额下回外侧和胼胝体区域内的脑血流显著升高，提示这些部位的脑功能可能存在功能性改变，说明抑郁症大学生在认知方面存在行为抑制，而且该问题与特定部位的脑机制有关。

Methods MRI findings of 26 cases with pathologically-proved PCNSL were analyzed retrospectively and the study emphasized on the location, signal feature, contrast-enhanced type, perilesional edema, ependymal seeding, and infiltration of corpus callosum.

Results According the MRI characteristric of hypoxic-ischemic encephalopath sequela:(1)The most common findings were white matter injury in 47 cases:①Periventricular leukomalacia in 23 cases;②Selective cerebral neuronal necrosis of basilar node lentiform nucleus and optic colliculus in 9 cases;③Corpus callosum damaged in 15 cases;(2)The most damaged of grey matter in 18 cases;(3)Focal or multifocal ischemic crerbral intenerate in 9 cases;(4)Diffuse crerbral injury in 5 cases.
