The hindbrain and cortico-reticular pathway in adolescent idiopathic scoliosis
AIM: To characterise the corticoreticular pathway (CRP) in a case -control cohort of adolescent idiopathic scoliosis (AIS) patients using high -resolution slice -accelerated readoutsegmented echo -planar diffusion tensor imaging (DTI) to enhance the discri ...
W B Saunders Co Ltd2024Fast refacing of MR images with a generative neural network lowers re-identification risk and preserves volumetric consistency
Jean-Philippe Thiran, Tobias Kober, Bénédicte Marie Maréchal, Jonas Richiardi
With the rise of open data, identifiability of individuals based on 3D renderings obtained from routine structural magnetic resonance imaging (MRI) scans of the head has become a growing privacy concern. To protect subject privacy, several algorithms have ...
Wiley2024A Multicenter Longitudinal MRI Study Assessing LeMan-PV Software Accuracy in the Detection of White Matter Lesions in Multiple Sclerosis Patients
Meritxell Bach Cuadra, Tobias Kober, Bénédicte Marie Maréchal, Cristina Granziera, Muhamed Barakovic, Lester Melie Garcia, Ricardo Alberto Corredor Jerez, Po-Jui Lu
BackgroundDetecting new and enlarged lesions in multiple sclerosis (MS) patients is needed to determine their disease activity. LeMan-PV is a software embedded in the scanner reconstruction system of one vendor, which automatically assesses new and enlarge ...
WILEY2023High field brain proton magnetic resonance spectroscopy and volumetry in children with chronic, compensated liver disease-A pilot study
Lijing Xin, Cristina Ramona Cudalbu, Bénédicte Marie Maréchal, Sarah Lachat
Background: There is increasing evidence that children or young adults having acquired liver disease in childhood display neurocognitive impairment which may become more apparent as they grow older. The molecular, cellular and morphological underpinnings o ...
ACADEMIC PRESS INC ELSEVIER SCIENCE2023Interrelation between cardiac and brain small-vessel disease: a pilot quantitative PET and MRI study
Bénédicte Marie Maréchal, Ricardo Alberto Corredor Jerez
Background: Small-vessel disease (SVD) plays a crucial role in cardiac and brain ischemia, but little is known about potential interrelation between both. We retrospectively evaluated 370 patients, aiming at assessing the interrelation between cardiac and ...
London2023Plasma neurofilament light and phosphorylated tau 181 as biomarkers of Alzheimer's disease pathology and clinical disease progression
Bénédicte Marie Maréchal, Jonas Richiardi, Christopher Clark
BackgroundTo assess the performance of plasma neurofilament light (NfL) and phosphorylated tau 181 (p-tau181) to inform about cerebral Alzheimer's disease (AD) pathology and predict clinical progression in a memory clinic setting.MethodsPlasma NfL and p-ta ...
BMC2021Validating atlas-based lesion disconnectomics in multiple sclerosis: A retrospective multi-centric study
Tobias Kober, Bénédicte Marie Maréchal, Reto Meuli, Jonas Richiardi, Mario Joao Fartaria de Oliveira
The translational potential of MR-based connectivity modelling is limited by the need for advanced diffusion imaging, which is not part of clinical protocols for many diseases. In addition, where diffusion data is available, brain connectivity analyses rel ...
2021Automated assessment of paramagnetic rim lesions in multiple sclerosis patients with 3T and 7T MP2RAGE
Jean-Philippe Thiran, Meritxell Bach Cuadra, Tobias Kober, Bénédicte Marie Maréchal, Cristina Granziera, Francesco La Rosa
Paramagnetic rim lesions (PRL) in multiple sclerosis are chronic inflammatory lesions depicted in susceptibility-based MRI where high PRL lesion burden has been associated with a more aggressive disease course. As their visual detection is subjective and t ...
ISMRM2021MRI-based brain volumetry and retinal optical coherence tomography as the biomarkers of outcome in acute methanol poisoning
Tobias Kober, Bénédicte Marie Maréchal
Background: Basal ganglia lesions are typical findings on magnetic resonance imaging (MRI) of the brain in survivors of acute methanol poisoning. However, no data are available on the association between the magnitude of damaged brain regions, serum concen ...
