Bevacizumab: radiation combination produces restricted diffusion on brain MRI

From Diffusion MRI to Brain

Computational Brain Connectivity Using Diffusion MRI

of “Computational Brain Connectivity Using Diffusion MRI” by Çağatay Demiralp, Ph.D., Brown University, May 2013. This dissertation shows that qualitative and quantitative characterization of patterned structures in brain connectivity data obtained using diffusion MRI not only improves the exploration of the intricate space of brain connectivity but also provides clinically meaningful measures,...

From Diffusion Mri to Brain Connectomics

The success of diffusion MRI is deeply rooted in the fact that during their micrometric random displacements water molecules explore tissue microstructure. Hence by labeling magnetically spins of displaced water, diffusion MRI provides us with exquisite information about the sizes and orientations on the multiple compartments present inside an imaging voxel. Through the causal relation between ...

Diffusion MRI for Characterising Childhood Brain Tumours

Diffusion MRI of Brain Connectivity and Microstructure:

What is a “diffusion coefficient” or “diffusion tensor” in living tissue, anyway? While the measurement of the self-diffusivity in an NMR tube represents a "gold standard", in complex media particularly in living tissue, water “diffusivity” ceases to have a clear meaning or definition. The apparent diffusion coefficient (ADC) and apparent diffusion tensor (ADT) concepts were introduced to answe...
