In vivo assessment of myelination by phase imaging at high magnetic field

Rolf Gruetter, José Pedro Rebelo Ferreira Marques, Rajika Maddage

The present study evaluated the potential of using the phase of T-2* weighted MR images to characterize myelination during brain development and pathology in rodents at 9.4 T. Phase contrast correlated with myelin content assessed by histology and suggests ...

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 ...

On the origin of the MR image phase contrast: An in vivo MR microscopy study of the rat brain at 14.1 T

Rolf Gruetter, José Pedro Rebelo Ferreira Marques, Rajika Maddage

Recent studies at high magnetic fields using the phase of gradient-echo MR images have shown the ability to unveil cortical substructure in the human brain. To investigate the contrast mechanisms in phase imaging, this study extends, for the first time, ph ...
