Relationship between timed 25-foot walk and diffusion tensor imaging in multiple sclerosis
Multiple Sclerosis Journal - Experimental, Translational and Clinical, 2016 Objective/Background The majority of multiple sclerosis patients experience impaired walking ability, which impacts quality of life. Timed 25-foot walk is commonly used to gauge gait impairment but results can be broadly variable.

An error analysis of probabilistic fibre tracking methods: average curves optimization [PDF]
, 2009 Fibre tractography using diffusion tensor imaging is a promising method for estimating the pathways of white matter tracts in the human brain. The success of fibre tracking methods ultimately depends upon the accuracy of the fibre tracking algorithms and

ROLE OF MRI DIFFUSION TENSOR IMAGING IN ASSESSMENT OF RESPONSE OF NORMAL APPEARING WHITE MATTER IN CASE OF MULTIPLE SCLEROSIS. [PDF]
Ain Shams Medical Journal, 2022 Background: Multiple sclerosis (MS) is an autoimmune inflammatory demyelinating disease of brain & spinal cord. Conventional MRI (T1, T2, FLAIR, enhancedT1) provides information of morphology of demyelinating plaques, but irrelevant to give details ...

Diffusion tensor imaging in schizophrenia
European Psychiatry, 2008 AbstractDiffusion tensor imaging (DTI) is a magnetic resonance imaging technique that is increasingly being used for the non-invasive evaluation of brain white matter abnormalities. In this review, we discuss the basic principles of DTI, its roots and the contribution of European centres in its development, and we review the findings from DTI studies ...

Diffusion Tensor Imaging [PDF]
, 2014 Diffusion tensor imaging (DTI) is a method of specifying and visualizing the functional integrity of white matter tracts that contribute to the functional and structural connectivity among different brain regions through the examination of water diffusion through tissue.

Diffusion tensor distribution imaging [PDF]
NMR in Biomedicine, 2019 Conventional diffusion MRI yields voxel‐averaged parameters that suffer from ambiguities for heterogeneous anisotropic materials such as brain tissue. Using principles from solid‐state NMR spectroscopy, we have previously introduced the shape of the diffusion encoding tensor as a separate acquisition dimension that disentangles isotropic and ...

Multi-centre reproducibility of diffusion MRI parameters for clinical sequences in the brain. [PDF]
, 2015 The purpose of this work was to assess the reproducibility of diffusion imaging, and in particular the apparent diffusion coefficient (ADC), intra-voxel incoherent motion (IVIM) parameters and diffusion tensor imaging (DTI) parameters, across multiple ...

Effective diffusion tensor computed by homogenization [PDF]
, 2013 The convergence of the long-time apparent diffusion tensor of diffusion magnetic resonance imaging (dMRI) to the effective diffusion tensor obtained by mathematical homogenization theory was considered for two-compartment geometric models containing non ...
