Testing the variability of Diffusion Spectrum Imaging (DSI): Inter- and intra-site comparison on "identical" 3T scanners

Jean-Philippe Thiran, Reto Meuli, François Lazeyras, Alia Lemkaddem, Gunnar Krüger, Alessandro Daducci

Multi-center neuroimaging studies have more power than smaller ones to conduct sophisticated studies of basic neuroanatomy and clinical disorders. One important confound of combining images obtained from different scanners is the potential for scanner effe ...

Who said fat is bad? Skull-stripping benefits from additional fat image

Reto Meuli, Delphine Ribes Lemay, Gunnar Krüger, Tobias Kober

Being a preliminary step for many clinical applications and analyses, accurate skull-stripping is a key challenge in MR brain imaging. One of its major difficulties arises from the contrast similarities at brain/non-brain tissue interfaces, in particular b ...

Topography of EEG multivariate phase synchronization in early Alzheimer's disease

Martin Hasler, Reto Meuli, Mahdi Jalili

Alzheimer's disease (AD) is likely to disrupt the synchronization of the bioelectrical processes in the distributed cortical networks underlying cognition. We analyze the surface topography of the multivariate phase synchronization (MPS) of multichannel EE ...

Attenuated asymmetry of functional connectivity in schizophrenia: A high-resolution EEG study

Martin Hasler, Reto Meuli, Mahdi Jalili, Kim Do

The interhemispheric asymmetries that originate from connectivity-related structuring of the cortex are compromised in schizophrenia (SZ). Under the assumption that such abnormalities affect functional connectivity, we analyzed its correlate-EEG synchroniz ...

On the reproducibility and anatomical correspondence of DSI tractography

Jean-Philippe Thiran, Xavier Gigandet, Patric Hagmann, Reto Meuli, Gunnar Krüger, Cristina Granziera, Alessandro Daducci, Leila Cammoun

Diffusion spectrum imaging (DSI) is increasingly explored in clinical research. The quantitative value of the DSI technique, however, has still to be established. In this context, a better understanding of the reproducibility and the anatomical corresponde ...

White matter maturation reshapes structural connectivity in the late developing human brain

Jean-Philippe Thiran, Patric Hagmann, Reto Meuli, Van Jay Wedeen, Leila Cammoun, Olaf Sporns

From toddler to late teenager, the macroscopic pattern of axonal projections in the human brain remains largely unchanged while undergoing dramatic functional modifications that lead to network refinement. These functional modifications are mediated by inc ...

GLOBAL AND LOCAL CONNECTIVITY CHANGES IN SCHIZOPHRENIA INVESTIGATED BY DIFFUSION CONNECTOME

Jean-Philippe Thiran, Djalel Eddine Meskaldji, Xavier Gigandet, Patric Hagmann, Reto Meuli, Leila Cammoun

Local landmark-based registration for fMRI group studies of nonprimary auditory cortex

Jean-Philippe Thiran, Ruth Campos Casillas, Reto Meuli, Dragana Viceic

Interindividual functional and structural brain variability is a major problem in group studies, in which very focal activations are expected. Architectonic studies have shown that the human primary auditory area, which is located with a great constancy on ...

Diffusion Spectrum Imaging Shows the Structural Basis of Functional Cerebellar Circuits in the Human Cerebellum In Vivo

Reto Meuli, Van Jay Wedeen, Nouchine Hadjikhani, Cristina Granziera

Background: The cerebellum is a complex structure that can be affected by several congenital and acquired diseases leading to alteration of its function and neuronal circuits. Identifying the structural bases of cerebellar neuronal networks in humans in vi ...

Automatic quality assessment in structural brain magnetic resonance imaging

Jean-Philippe Thiran, Reto Meuli, Bénédicte Marie Maréchal, Gunnar Krüger

MRI has evolved into an important diagnostic technique in medical imaging. However, reliability of the derived diagnosis can be degraded by artifacts, which challenge both radiologists and automatic computer-aided diagnosis. This work proposes a fully-auto ...

Automatic quality assessment in structural brain magnetic resonance imaging

Jean-Philippe Thiran, Reto Meuli, Bénédicte Marie Maréchal, Gunnar Krüger

Quality assessment of MRI is of great importance to derive reliable diagnostic information. As automated quantitative image analysis is being increasingly used in routine, automated measures of quality are needed. Based on a single magnitude image, we prop ...

Predicting Human Resting-State Functional Connectivity from structural Connectivity

Jean-Philippe Thiran, Xavier Gigandet, Patric Hagmann, Reto Meuli, Leila Cammoun, Olaf Sporns

In the cerebral cortex, the activity levels of neuronal populations are continuously fluctuating. When neuronal activity, as measured using functional MRI (fMRI), is temporally coherent across 2 populations, those populations are said to be functionally co ...

Diffusion MR Image Segmentation: Towards Global Brain Connectivity Analysis

Jean-Philippe Thiran, Xavier Gigandet, Patric Hagmann, Reto Meuli, Leila Cammoun

The exploration of the human connectome, a term denoting the global structural connectivity of the brain, is accessible to MRI at millimeter and centimeter scales. In this paper, we propose a methodology to map the connectome by constructing normalized who ...

Mapping the Structural Core of Human Cerebral Cortex

Pascal Hagmann, Xavier Gigandet, Patric Hagmann, Reto Meuli, Leila Cammoun, Olaf Sporns

Structurally segregated and functionally specialized regions of the human cerebral cortex are interconnected by a dense network of cortico-cortical axonal pathways. Using diffusion spectrum imaging we noninvasively map these pathways within and across cort ...

The Structural Core of Human Cerebral Cortex and its relation to the brain s default network

Xavier Gigandet, Reto Meuli, Leila Cammoun, Olaf Sporns

Human cerebral cortex contains an uncertain number of structurally segregated regions interconnected by a dense network of axonal pathways. Using DSI, we map these pathways in individual human subjects. An analysis of the resulting large-scale structural b ...

Thalamic nuclei clustering on High Angular Resolution Diffusion Images

Pascal Hagmann, Jean-Philippe Thiran, Patric Hagmann, Reto Meuli, Azzurra Grassi, Leila Cammoun

Thalamic nuclei can be distinguished by their characteristic fiber orientations, which influence the diffusion. Fiber orientations are relatively aligned within a nucleus due to the fact that the cerebrocortical striations within a nucleus all target the s ...

Adaptive FID-navigators for respiration monitoring in multi-slice fMRI applications

Reto Meuli, Rolf Gruetter, Wietske Van der Zwaag, Gunnar Krüger, Tobias Kober, José Pedro Rebelo Ferreira Marques

Functional magnetic resonance imaging (fMRI) measures activation-induced signal changes by means of the blood-oxygenation-level-depended (BOLD) contrast. Since signal changes are typically only 1-3%, the method is intrinsically sensitive to all signal inst ...
