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.

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 Capillary Phantom vs. Human Data: Outcomes for Reconstruction Methods Depend on Evaluation Medium

Frontiers in Neuroscience, 2016
Purpose: Diffusion MRI provides a non-invasive way of estimating structural connectivity in the brain. Many studies have used diffusion phantoms as benchmarks to assess the performance of different tractography reconstruction algorithms and assumed that ...

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 ...

The ultrastructural and morphological characteristics of the anterior cruciate ligament of the pig: a study using 7.0-Tesla diffusion tensor imaging

Journal of International Medical Research, 2022
Objective Diffusion tensor imaging research on the anterior cruciate ligament (ACL) is limited, and no study has revealed the ACL fibrous microstructure by 7.0-Tesla magnetic resonance imaging.

Defining Meyer's loop-temporal lobe resections, visual field deficits and diffusion tensor tractography [PDF]

, 2009
Anterior temporal lobe resection is often complicated by superior quadrantic visual field deficits (VFDs). In some cases this can be severe enough to prohibit driving, even if a patient is free of seizures.
