Exact analytical PGSE signal for diffusion confined to a cylindrical surface using a spectral Laplacian formalism
Erick J Canales-Rodríguez, Chantal M. W. Tax, Juan Manuel Górriz +3
Objective. To derive an exact analytical expression for the diffusion MRI signal arising from diffusion confined to a cylindrical surface under finite rectangular pulsed-gradient s…
Multi-compartment diffusion MRI, T2 relaxometry and myelin water imaging as neuroimaging descriptors for anomalous tissue detection
Elda Fischi-Gomez, Jonathan Rafael-Patino, Marco Pizzolato +5
Multiple sclerosis (MS) is an inflammatory and neurodegenerative disease characterized by diffuse and focal areas of tissue loss. Conventional MRI techniques such as T1-weighted an…
A Signal Peak Separation Index for axisymmetric B-tensor encoding
Gaëtan Rensonnet, Jonathan Rafael-Patiño, Benoît Macq +3
Diffusion-weighted MRI (DW-MRI) has recently seen a rising interest in planar, spherical and general B-tensor encodings. Some of these sequences have aided traditional linear encod…
Robust Monte-Carlo Simulations in Diffusion-MRI: Effect of the substrate complexity and parameter choice on the reproducibility of results
Jonathan Rafael-Patino, David Romascano, Alonso Ramirez-Manzanares +3
Monte-Carlo Diffusion Simulations (MCDS) have been used extensively as a ground truth tool for the validation of microstructure models for Diffusion-Weighted MRI. However, methodol…
