2020年7月7日 · The aims of this study were to determine the DTI parameters changes of bilateral GONs and DRG in unilateral CGH, as well as the grading value of DTI for severe headache. We also determined the correlation of DTI parameters with the headache index (HI), and the course of the disease (the period elapsed since the symptom started).

2020年7月1日 · The purpose of this study was determining diffusion tensor imaging (DTI) parameters of bilateral GONs and dorsal root ganglia (DRG) in unilateral cervicogenic headache as well as the grading value of DTI for severe headache. The correlation between DTI parameters and clinical characteristics was evaluated.

Processing included: DRG segmentation (MD.ai), 3D volume (MorphACE), DTI (spherical harmonic and Constant Solid Angle). ADC, FA and volume were compared between HVs, asymptomatic and symptomatic DRG and correlated with stenosis grades using paired t-tests. Results: 25 patients and 5 HVs DTI scans were analyzed (34 patients and 10 HVs for volume).

DWI（Diffusion Weighted Imaging）扩散加权成像是临床中最常用的MRI功能成像技术之一，目前基本上在很多部位扫描中都会增加，大家对于DWI也是非常熟悉了，公众号里写了很多关于DWI的文章。 前文链接： 关于Diffusion Weighted Imaging（DWI）中文翻译之讨论. 如何做好弥散（DWI）序列及DWI扫描参数技巧. 为什么不能只看DWI图来判断弥散受限，还有结合ADC图 DWI-TSE无形变扩散成像. 扩散加权成像中B值的数学物理含义. 本期内容则开始讲究DTI。 其实前 …

2023年2月9日 · 弥散张量成像（diffusion tensor imaging，DTI）是一种基于常规磁共振影像技术发展出的新兴影像表达方法。 DTI是MRI的一种特殊形式，不仅可以显示每一个体素的信号强度，而且还能够计算3维空间中张量方向的具体数据。 然后将每一个体素展现出的单个箭头根据神经束方向的差异进行整理，生成一组方向箭头。 再经由图像数据的处理将每一组的方向箭头进行加工，形成神经束的线性图像。 大脑中的白质纤维束呈几何形式排列，由于弥散磁共振成像能够清晰 …

2024年5月8日 · 与结构MR相比，DTI图像分辨率低，且更容易发生几何畸变，Elements Distortion Correction模块可以对DTI原始图像进行点对点畸变矫正，然后就进行图像融合，这就是Elements特有的弹性融合技术，它可以精准的将自动分割的种子点映射到DTI原始影像。
