Several observations suggest that the transmission of myocardial forces is influenced in part by the spatial arrangement of the myocytes aggregated together within ventricular mass. Our aim was to assess, using diffusion tensor magnetic resonance imaging (DT-MRI), any differences in the three-dimensional arrangement of these myocytes in the normal heart compared with the hypertrophic murine myo...

We investigated whether the functional connections to the primary sensorimotor cortex (SMC) at rest are abnormal in 26 patients with amyotrophic lateral sclerosis (ALS) and whether such changes are related to the corticospinal tract (CST) damage, measured using diffusion tensor magnetic resonance imaging (DT MRI). ALS patients versus controls showed a significantly increased functional connecti...

Reliable prognostic markers of primary progressive (PP) multiple sclerosis evolution are still needed. Diffusion tensor (DT) MRI can quantify normal-appearing white matter (NAWM) and grey matter (GM) damage in multiple sclerosis patients. We investigated whether conventional and DT-MRI-derived measures can predict the long-term clinical evolution of PP multiple sclerosis. In 54 PP multiple scle...

We provide scientific background information and personal accounts relating to our publication of "Microstructural and Physiological Features of Tissues Elucidated by Quantitative-Diffusion-Tensor MRI" in the Journal of Magnetic Resonance B. This paper provided a framework for measuring and mapping intrinsic features of diffusion anisotropy obtained from diffusion tensor MRI (DTI) data.

Introduction Recently, a great deal of research has focused upon investigating the relationship between the functional and structural networks that make up the brain. A popular approach is to use functional MRI (fMRI) to identify functionally activated regions of the cortex and diffusion tensor MRI (DT-MRI) to examine structural properties of the white matter pathways that connect the functiona...

Visualizing the human brain using diffusion tensor magnetic resonance imaging (DT-MRI) data has been a key technique to study the structure of the human brain and its connectivity. The challenge is to find a method that best exploits the data and serves as a model for visualization and connectivity analysis. This paper presents a novel method of visualizing the human brain structure with a mini...

In recent years, musicians have been increasingly recruited to investigate grey and white matter neuroplasticity induced by skill acquisition. The development of Diffusion Tensor Magnetic Resonance Imaging (DT-MRI) has allowed more detailed investigation of white matter connections within the brain, addressing questions about the effect of musical training on connectivity between specific brain...

PURPOSE To analyze in vivo the diffusion tensor magnetic resonance imaging (DT-MRI) properties of the intraorbital optic nerve at two different levels: Proximal to the optic nerve head (ONH) and distal to the ONH at the level of the orbital apex in glaucoma patients. METHODS Twenty-four patients with primary open-angle glaucoma were examined. The categorization into early and severe glaucoma ...

BACKGROUND Diffusion tensor magnetic resonance imaging (DT MRI) has the potential to provide in vivo information about tissue microstructure. In multiple sclerosis (MS), DT MRI has disclosed the presence of occult structural damage in the normal-appearing brain tissues. OBJECTIVE To investigate whether DT MRI is sensitive to longitudinal changes of brain damage that may occur beyond the resol...
