dti是一种对白质结构改变、白质完整性及轴突的结构性连接改变很敏感的非侵入性影像学检查方法。 用这种迷散张量的一个连接的方式，可以把它作为一个生物标记，然后结合患者运动捕捉的参数，可以在特别早期的进行诊断。

2023年11月3日 · Introduction: The aim of the study was to construct and validate a nomogram that combines diffusion tensor imaging (DTI) parameters and clinically relevant features for predicting the progression of mild cognitive impairment (MCI) to Alzheimer's disease (AD).

Review: This manuscript will briefly review the animal and histological data supporting the important role of myelin following TBI, contributions and shortcomings of the use of diffusion tensor imaging (DTI) in mild TBI and the utility of multi-component relaxometry (MCR) techniques as a method for improved visualizing of white matter ...

2024年8月15日 · New MCR-based biomarkers calculated from the Diffusion Tensor are proposed to improve the identification of breast tumors. PLS-DA, Random Forest, Logistic regression and SVM have been applied to discriminate between healthy and lesion tissues.

Multicomponent analysis of T1 and T2 relaxation data, or multicomponent relaxometry (MCR), is a quantitative imaging technique that is sensitive and specific to myelin content alteration. In the past, MCR has been associated with lengthy imaging times, but a new, faster MCR technique (mcDESPOT) has made quantitative analysis of myelin content ...

随着dti技术应用范围的不断扩大、结果的一致性和稳健性的不断提高，dti有望在疾病治疗规划、临床前标志物检测和微结构异常等方面发挥重要的作用；dti研究提供的结构-功能相关性也有望在临床上得到应用，将成为临床影像常规的一部分。

弥散张量成像(dti)，是一种描述大脑结构的新方法，是核磁共振成像(mri)的特殊形式。 举例来说，如果说核磁共振成像是追踪水分子中的氢原子，那么弥散张量成像便是依据水分子移动方向制图。

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 …

2023年8月26日 · To enhance feature learning between drugs and targets, we propose a novel model based on deep learning for DTI task called MCL-DTI which uses multimodal information of drug and learn the representation of drug–target interaction for drug–target prediction.

2013年7月27日 · DTI is a variant of MRI that measures the diffusion of water molecules in brain tissue. Here we set out to assess which standard DTI measures may best identify neuroanatomical differences between AD, MCI, and normal aging.
