Comparative review of algorithms and methods for chemical‐shift‐encoded quantitative fat‐water imaging Open
Purpose To propose a standardized comparison between state‐of‐the‐art open‐source fat‐water separation algorithms for proton density fat fraction (PDFF) and quantification using an open‐source multi‐language toolbox. Methods Eight recent o…

Combining sodium <span>MRI</span> , proton <span>MR</span> spectroscopic imaging, and intracerebral <span>EEG</span> in epilepsy Open
Whole brain ionic and metabolic imaging has potential as a powerful tool for the characterization of brain diseases. We combined sodium MRI ( 23 Na MRI) and 1 H‐MR Spectroscopic Imaging ( 1 H‐MRSI), assessing changes within epileptogenic n…

Grey-matter sodium concentration as an individual marker of multiple sclerosis severity Open
Objective: Quantification of brain injury in patients with variable disability despite similar disease duration may be relevant to identify the mechanisms underlying disability in multiple sclerosis (MS). We aimed to compare grey-matter so…

Respiratory‐triggered quantitative MR spectroscopy of the human cervical spinal cord at 7 T Open
Purpose Ultra‐high field H MR spectroscopy (MRS) is of great interest to help characterizing human spinal cord pathologies. However, very few studies have been reported so far in this small size structure at these fields due to challenging…

Evaluation of the Sensitivity of Inhomogeneous Magnetization Transfer (ihMT) MRI for Multiple Sclerosis Open
The sensitivity of the inhomogeneous magnetization transfer technique for MS was highlighted by the reduction in the inhomogeneous magnetization transfer ratio in MS lesions and in normal-appearing WM of patients compared with controls. St…

Creatine, Glutamine plus Glutamate, and Macromolecules Are Decreased in the Central White Matter of Premature Neonates around Term Open
Preterm birth represents a high risk of neurodevelopmental disabilities when associated with white-matter damage. Recent studies have reported cognitive deficits in children born preterm without brain injury on MRI at term-equivalent age. …
