Purpose: Diffusion Tensor Imaging, as a new functional magnetic resonance Imaging technology based on diffusion weight imaging,is currently the only non-invasive method to show the white matter fibers information of line, direction, arrangement,compactness, and myelinization.Seizures could affect the other brain regions by epilepsy pathway.The white matter abnormalities in temporal lobe epilepsy patients with hippocampal sclerosis(TLE-HS)extended beyond the hippocampal and temporal lobe.This research aimed at the white matter abnormalities in TLE-HS based on different diffusion tensor imaging(DTI)analysis.

目的:常规X线或CT检查常不能发现膝关节韧带的损伤,而MRI检查具有良好的软组织对比度和高空间分辨率,对膝关节韧带损伤可清楚显示,可作为膝关节韧带损伤检查的重要或首选手段.在MR矢状位不同角度下扫描成像显示膝关节前交叉韧带,探讨膝关节前交叉韧带的最佳显示.
目的:探讨在2D MRCP扫描中,图像质量不佳情况下,利用相位校正技术(Phase scout),进行3D MRCP扫描,在上腹部胆道水成像诊断中的应用价值.方法:选取呼吸憋气不佳患者60例,年龄45岁-80岁,在本院Simenz 1.5T Aera磁共振(软件已升级至D13)下,采用平静自由呼吸,利用相位校正技术进行3D MRCP扫描,该方法所采用的主要扫描参数如下:FoV read:380-4
目的:了解多层螺旋CT中的"层"、"排"、"列"的概念.方法:多层CT(multi-slice CT),是指通过扫描一周后可以同时获得多层图像的CT,一般采用多排探测器(mulit-row detector)技术完成.随着科技的不断进步,排与层的概念越不容易区分,以飞利浦多层CT为例,它的4层、8层、16层CT均由24排探测器构成,只是通过技术手段开通不同数量的探测器通道以实现层数的不同.
