2019年6月22日 · Locating the corticospinal tract (CST) Diffusion tensor imaging, or DTI, is an advanced MRI technique in which the asymmetric motion of water is used to map out specific properties in the brain. One application of DTI is called tractography, or identifying the specific tracts of neurons which pass through the brain.

2005年4月1日 · METHODS: DTI findings in four patients with masses near the CST and not involving motor cortex were retrospectively reviewed and compared with contralateral motor strength. CST involvement was determined from anisotropy and …

目前磁共振扩散张量成像(diffusion tensor imaging，DTI)依然是评估活体脑CST结构特征的唯一有效途径。 基于DTI量化脑卒中患者CST损伤的研究方法主要包括：(1)手动勾画感兴趣区(region of interest，ROI)方法。

We aimed to determine whether a diffusion tensor imaging (DTI)-derived CST metric predicts distal upper extremity (UE) motor improvements in chronic stroke survivors.

2022年7月21日 · Diffusion tensor imaging (DTI) can assess the structural integrity of the corticospinal tract (CST) in vivo. We aimed to investigate whether CST DTI metrics after intracerebral haemorrhage (ICH) are associated with 6-month functional outcome and can improve the predictive performance of the existing ICH score.

2017年1月1日 · DTI metrics of fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity (AD) and radial diffusivity (RD) were also determined in four regions of interest (ROIs) along the CST, namely: cerebral peduncle (CP), posterior limb of internal capsule (PLIC), centrum semiovale at top of lateral ventricle (CSoLV) and subcortical to primary ...

The structural integrity of the corticospinal tract (CST) after stroke is closely linked to the degree of motor impairment. Simple and reliable methods of assessing white matter integrity within the CST would facilitate the use of this measure in ...

2015年3月14日 · CSD is superior to DTI-based tractography in detecting differences in diffusion characteristics between the nondominant healthy control and ipsilesional CST. CSD measures of microstructure tissue properties related to more motor outcomes than DTI measures did.

2018年7月1日 · Our results provide robust evidence that among seven different DTI-derived estimates of CST, 3-D individual CST tractography-based FA asymmetry (E1) is the best measure for characterizing CST structure in this cohort of chronic stroke survivors with mild-to …

2022年1月4日 · 目的:研究急性脑梗死患者大脑脚皮质脊髓束(cst)投射区弥散张量成像(dti)参数值与神经系统功能评分的关系.方法:急性脑梗死患者52例纳入研究.所有患者均进行3.0t mri常规检查以及dti检查,测量患者患侧及健侧大脑脚cst投射区dti参数,并分析大脑脚dti参数与患者美国国立卫生研究院卒中量表(nihss)评分的 ...
