Fast and robust estimation of NODDI parameters using non-Gaussian noise models and spatial regularization

Jean-Philippe Thiran, Erick Jorge Canales Rodriguez, Alessandro Daducci

In this study, we developed a robust inversion algorithm to estimate the Neurite Orientation Dispersion and Density Imaging (NODDI) model. It is based on the Accelerated Microstructure Imaging via Convex Optimization (AMICO) framework. However, in contrast ...

High spatio-temporal resolution in functional MRI with 3D echo planar imaging using cylindrical excitation and a CAIPIRINHA undersampling pattern

Wietske Van der Zwaag, José Pedro Rebelo Ferreira Marques, Daniel Gallichan, Mayur Narsude, Olivier Benoit Thomas Reynaud

The combination of 3D echo planar imaging (3D-EPI) with a 2D-CAIPIRINHA undersampling scheme provides high flexibility in the optimization for spatial or temporal resolution. This flexibility can be increased further with the addition of a cylindrical exci ...

Case-Control Discrimination Through Effective Brain Connectivity

Luca Dodero

Functional and structural connectivity convey different information about the brain. The integration of these different approaches is receiving growing attention from the research community, as it can shed new light on brain functions. This manuscript prop ...

Large Volume Imaging of Rodent Brain Anatomy with Emphasis on Selective Plane Illumination Microscopy

Jean Pierre Ghobril

Inside the human brain there are 86 Billion neurons exchanging electrical impulses to allow reaction, homoeostasis and intelligence. Their coarse organization has been described, leaving us with a fair understanding of macrocircuitry. The microcircuitry of ...
