Structural Graph Analysis of Left and Right Temporal Lobe Epilepsy using Diffusion Spectrum Imaging

Jean-Philippe Thiran, Alessandro Daducci, Alia Lemkaddem, François Lazeyras

Patients with Temporal Lobe Epilepsy (TLE) suffer from widespread subtle white matter abnormalities and abnormal functional connectivity extending beyond the affected lobe, as revealed by volumetric and functional MRI studies. Diffusion Magnetic Resonance ...

Decline of Fiber Tract Integrity Over the Adult Age Range: A Diffusion Spectrum Imaging Study

Kieran O'Brien

Purpose: We applied a novel diffusion spectrum imaging (DSI) acquisition to determine associations between aging and subcortical fiber tract integrity. Materials and Methods: We studied 35 cognitively healthy subjects (17 women), spanning the adult age ran ...

Quantitative comparison of reconstruction methods for intra-voxel fiber recovery from diffusion MRI

Jean-Philippe Thiran, Yves Wiaux, Erick Jorge Canales Rodriguez, Alonso Ramirez Manzanares, Alessandro Daducci, Maxime Descoteaux, Ying-Chia Lin, Gloria Menegaz, Mathews Jacob

Validation is arguably the bottleneck in the diffusion MRI community. This paper evaluates and compares 20 algorithms for recovering the local intra-voxel fiber structure from diffusion MRI data and is based on the results of the "HARDI reconstruction chal ...

Structural connectomics in brain diseases

Jean-Philippe Thiran, Alessandra Griffa, Patric Hagmann, Philipp Baumann

Imaging the connectome in vivo has become feasible through the integration of several rapidly developing fields of science and engineering, namely magnetic resonance imaging and in particular diffusion MRI on one side, image processing and network theory o ...

The CONNECT project: combining macro- and micro-structure

In recent years, diffusion MRI has become an extremely important tool for studying the morphology of living brain tissue, as it provides unique insights into both its macrostructure and microstructure. Recent applications of diffusion MRI aimed to characte ...

The CONNECT project: Combining macro- and micro-structure

Tim Bjørn Dyrby

2013

Magnetic resonance imaging (MRI) has opened unprecedented avenues to observe the human brain non-invasively. In particular, for about two decades, functional MRI (fMRI) has enabled to monitor brain function using the blood-oxygen-level-dependent (BOLD) con ...

EPFL2013

The principal aim of this thesis was to investigate human brain energy metabolism during physiological activation using proton (1H) magnetic resonance spectroscopy (MRS) at 7 Tesla (T). High magnetic fields (≥ 7 T) provide several advantages in human brain ...

Introduction: Medial Temporal Lobe Epilepsy (mTLE) with hippocampal sclerosis is the most frequent cause of drug-resistant focal epilepsy in adults. These patients suffer from widespread subtle white matter abnormalities and abnormal functional connectivit ...
