Test-retest variability of brain morphometry analysis: an investigation of sequence and coil effects

Bénédicte Marie Maréchal, Tobias Kober

Background: Precise and reliable brain morphometry analysis is critical for clinical and research purposes. The magnetization-prepared rapid gradient echo (MPRAGE), multi-echo MPRAGE (MEMPRAGE) and magnetization-prepared 2 rapid acquisition gradient echo ( ...

Serum GFAP in multiple sclerosis: correlation with disease type and MRI markers of disease severity

Bénédicte Marie Maréchal, Tobias Kober, Mario Joao Fartaria de Oliveira, Ricardo Alberto Corredor Jerez

Neurofilament light chain (NfL) has been demonstrated to correlate with multiple sclerosis disease severity as well as treatment response. Nevertheless, additional serum biomarkers are still needed to better differentiate disease activity from disease prog ...

Methanol Poisoning as an Acute Toxicological Basal Ganglia Lesion Model: Evidence from Brain Volumetry and Cognition

Bénédicte Marie Maréchal, Tobias Kober

Background Acute methanol poisoning leads to optic neuropathy and necrotic lesions of basal ganglia (BG) and subcortical white matter. Survivors of methanol poisoning exhibit long-term executive and memory deficits. Associations between brain volumetry par ...

Predicting Modafinil-Treatment Response in Poststroke Fatigue Using Brain Morphometry and Functional Connectivity

Bénédicte Marie Maréchal

Background and Purpose- Poststroke fatigue affects a large proportion of stroke survivors and is associated with a poor quality of life. In a recent trial, modafinil was shown to be an effective agent in reducing poststroke fatigue; however, not all patien ...

Episodic memory decline in Parkinson' s disease: relation with white matter hyperintense lesions and influence of quantification method

Meritxell Bach Cuadra, Bénédicte Marie Maréchal, Tobias Kober, Mario Joao Fartaria de Oliveira

The relation of white matter hyperintense lesions to episodic memory impairment in patients with Parkinson's disease (PD) is still controversial. We aimed at evaluating the relation between white matter hyperintense lesions and episodic memory decline in p ...

Prospective head motion correction using FID-guided on-demand image navigators

Reto Meuli, Rolf Gruetter, Bénédicte Marie Maréchal, Guillaume Bonnier, Gunnar Krüger, Tobias Kober, Tom Hilbert, Maryna Volodimirivna Waszak, Pavel Falkovskiy

PURPOSE: We suggest a motion correction concept that employs free-induction-decay (FID) navigator signals to continuously monitor motion and to guide the acquisition of image navigators for prospective motion correction following motion detection. METHODS: ...

Evaluating anorexia-related brain atrophy using MP2RAGE-based morphometry

François Lazeyras, Bénédicte Marie Maréchal, Tobias Kober, Alexis Roche

To evaluate brain atrophy in anorexic patients by automated cerebral segmentation with the magnetization-prepared 2 rapid acquisition gradient echo (MP2RAGE) MRI sequence. Twenty patients (female; mean age, 27.9 years), presenting consecutively for brain M ...

Comparison of accelerated T1-weighted whole-brain structural-imaging protocols

Jean-Philippe Thiran, Reto Meuli, Bénédicte Marie Maréchal, Tobias Kober, Alexis Roche, Pavel Falkovskiy

Imaging in neuroscience, clinical research and pharmaceutical trials often employs the 3D magnetisation-prepared rapid gradient-echo (MPRAGE) sequence to obtain structural T1-weighted images with high spatial resolution of the human brain. Typical research ...
