Diffusion tensor imaging (DTI) technique, which can be used to research the white matter of human brain non-invasively, provides more valuable information in the study of white matter abnormality, especially using fractional anisotropy (FA) images calculated from DTI data. Although there are many different DTI data analysis software, most of them are inconvenient to use and qualitative via visual...
Diffusion tensor magnetic resonance imaging (DT-MRI) data should be preprocessed before they are used to analyses for searching white matter fiber structure of human brain. Fractional anisotropy (FA) calculated by DTI data has been widely used because it can describe the anisotropy prosperity of white matter. This paper presents some evaluation criterions to optimize the image preprocessing procedure...
Diffusion tensor imaging (DTI) is a magnetic resonance imaging technique that can estimate the directionality of fibers and the microstructural of white matter in human brain. DTI researches have demonstrated that demyelinations existed in white matter of Alzheimer's disease (AD) patients mainly by fractional anisotropy (FA) and apparent diffusion constant (ADC). FA or ADC is usually used to reveal...
Magnetic resonance diffusion tensor imaging (MR-DTI) as a noninvasive technique can investigate the cerebral white matter architecture based on the directional information of diffusion that is related to fiber tract. With the development of DTI technique in recent years, more and more studies of combining fMRI with DTI are used to explore the relationships between functional connectivity and its structural...
