A diffusion MRI model for random walks confined on cylindrical surfaces: towards non-invasive quantification of myelin sheath radius

Jean-Philippe Thiran, Erick Jorge Canales Rodriguez, Elda Fischi Gomez

Introduction Quantifying the myelin sheath radius of myelinated axons in vivo is important for understanding, diagnosing, and monitoring various neurological disorders. Despite advancements in diffusion MRI (dMRI) microstructure techniques, there are curre ...

Removing Facial Features From Structural Mri Images Biases Visual Quality Assessment

Elda Fischi Gomez, Patric Hagmann, Jonas Richiardi, Oscar Esteban Rucavado Leandro, Thomas Sanchez

A critical step before data-sharing of human neuroimaging is removing facial features to protect individuals' privacy. However, not only does this process redact identifiable information about individuals, but it also removes non-identifiable information. ...

White adipose tissue distribution and amount are associated with increased white matter connectivity

Jean-Philippe Thiran, Gabriel Girard, Elda Fischi Gomez, Philipp Johannes Koch, Liana Okudzhava

Obesity represents a significant public health concern and is linked to various comorbidities and cognitive impairments. Previous research indicates that elevated body mass index (BMI) is associated with structural changes in white matter (WM). However, a ...

Amygdala volumes and associations with socio-emotional competencies in preterm youth: cross-sectional and longitudinal data

Elda Fischi Gomez, Vanessa Siffredi, Laura Ioana Gui, Petra Susan Hüppi

Background Socio-emotional difficulties often result from very preterm (VPT) birth. The amygdala's developmental trajectory, including its nuclei, has been recognized as a significant factor in observed difficulties. This study aims to assess the relations ...
