Structural abnormalities in the thalamus of migraine patients: a multi-parametric study at high field

Alessandro Daducci, Gunnar Krüger, Cristina Granziera, Nouchine Hadjikhani, David Paul Roger Romascano, Alexis Roche

2012

Bundle-Specific Axon Diameter Index as a New Contrast to Differentiate White Matter Tracts

Jean-Philippe Thiran, Alessandro Daducci, Gabriel Girard, Cristina Granziera, David Paul Roger Romascano, Maxime Descoteaux, Muhamed Barakovic, Giorgio Innocenti

In the central nervous system of primates, several pathways are characterized by different spectra of axon diameters. In vivo methods, based on diffusion-weighted magnetic resonance imaging, can provide axon diameter index estimates non-invasively. However ...

Central nervous system microbleeds in the acute phase are associated with structural integrity by DTI one year after mild traumatic brain injury: A longitudinal study

Jean-Philippe Thiran, Alessandro Daducci, David Paul Roger Romascano

Introduction: Several imaging modalities are under investigation to unravel the pathophysiological mystery of delayed performance deficits in patients after mild traumatic brain injury (mTBI). Although both imaging and neuropsychological studies have been ...

ELSEVIER URBAN & PARTNER SP Z O O2018

Voxel size matters: big voxels are required to generate realistic extra-axonal dMRI signals from Monte Carlo simulations

Jean-Philippe Thiran, Alessandro Daducci, David Paul Roger Romascano, Muhamed Barakovic, Jonathan Rafael Patino Lopez, Ileana Ozana Jelescu

2018

Non-parametric axon diameter distribution mapping with PGSE: reconstruction of uni- and multimodal distributions

Jean-Philippe Thiran, Alessandro Daducci, David Paul Roger Romascano, Muhamed Barakovic, Jonathan Rafael Patino Lopez

2018

Advanced MRI unravels the nature of tissue alterations in early multiple sclerosis

Jean-Philippe Thiran, Cristina Granziera, Gunnar Krüger, Djalel Eddine Meskaldji, Gloria Menegaz, David Paul Roger Romascano, Alexis Roche, Guillaume Bonnier, Ying-Chia Lin

In patients with multiple sclerosis (MS), conventional magnetic resonance imaging (MRI) provides only limited insights into the nature of brain damage with modest clinic-radiological correlation. In this study, we applied recent advances in MRI techniques ...

2014

Realistic 3D Fiber Crossing Phantom Models for Monte Carlo Diffusion Simulations

Jean-Philippe Thiran, Alessandro Daducci, Gabriel Girard, Muhamed Barakovic, David Paul Roger Romascano, Jonathan Rafael Patino Lopez, Gaëtan Olivier D Rensonnet

2018

In-vivo Bundle-Specific Axon Diameter Distributions Estimation across the Corpus Callosum

Jean-Philippe Thiran, Alessandro Daducci, Gabriel Girard, David Paul Roger Romascano, Muhamed Barakovic, Maxime Descoteaux

Over the last decade microstructure imaging has become commonly endorsed to estimate quantitative features of neuronal tissue. However, those techniques estimate the microstructure only locally. Microstructure informed tractography was recently proposed to ...
