Reducing acquisition time for microstructure imaging with spatially-regularized global optimization

Jean-Philippe Thiran, Yves Wiaux, Erick Jorge Canales Rodriguez, David Paul Roger Romascano, Alessandro Daducci, Anna Auria Rasclosa, Tim Bjørn Dyrby

Microstructure imaging with diffusion MRI (dMRI) is usually based on fitting models to the data using voxelwise nonlinear procedures that (i) are time consuming and (ii) need long acquisitions. Recently, we introduced the AMICO framework to accelerate the ...

B1+-mapping and B1+ inhomogeneity correction at high field

Florent Eggenschwiler

Magnetic resonance images acquired at the highest strength of the main magnetic field B0 are of interest since they highly benefit from an increased signal to noise ratio. At ultra high field strengths (B0 > 7 Tesla) images with more contrast and higher re ...

Low-Cost High-Performance MRI

Najat Salameh

Magnetic Resonance Imaging (MRI) is unparalleled in its ability to visualize anatomical structure and function non-invasively with high spatial and temporal resolution. Yet to overcome the low sensitivity inherent in inductive detection of weakly polarized ...

Phase-based manganese enhanced MRI, a new methodology to enhance brain cytoarchitectural contrast and study manganese uptake

Rolf Gruetter, José Pedro Rebelo Ferreira Marques, Rajika Maddage

Purpose As the magnetic susceptibility induced frequency shift increases linearly with magnetic field strength, the present work evaluates manganese as a phase imaging contrast agent and investigates the dose dependence of brain enhancement in comparison t ...

Wiley-Blackwell2014

Speed has always been a critical consideration in magnetic resonance imaging (MRI), promising dramatic gains in imaging speed, a reduction in motion and susceptibility artifacts, and ultimately increased throughput for clinical studies. This thesis present ...

Dinuclear Gd(III) Polyaminocarboxylates as Building Blocks for MRI Contrast Agents

Bibimaryam Mousavi

Magnetic resonance imaging (MRI) technique is at the forefront of biomedical and clinical imaging. Its superb spatial resolution, noninvasive nature and use of benign radiation outweigh its intrinsic low detection sensitivity. However paramagnetic relaxers ...

Magnetic resonance imaging of peripheral nerves: Differences in magnetization transfer

Giulio Gambarota

Introduction: Magnetic resonance imaging (MRI) is an excellent imaging modality for soft tissues. Magnetization transfer (MT) imaging is an MRI technique that is sensitive to the bound protons of macromolecules and therefore can aid in the assessment of ne ...

In vivo Structural Imaging of the Cerebellum, the Contribution of Ultra-High Fields

Rolf Gruetter, Wietske Van der Zwaag, José Pedro Rebelo Ferreira Marques

This review covers some of the contributions to date from cerebellar imaging studies performed at ultra-high magnetic fields. A short overview of the general advantages and drawbacks of the use of such high field systems for imaging is given. One of the bi ...
