Journal ArticleDOI
Artifacts and pitfalls in diffusion MRI.
TL;DR: In this article, specific problems that one may encounter when using MRI scanner gradient hardware for diffusion MRI, especially in terms of eddy currents and sensitivity to motion are reviewed.
Journal ArticleDOI
Dynamic study of blood-brain barrier closure after its disruption using ultrasound: a quantitative analysis.
Benjamin Marty,Benoit Larrat,Benoit Larrat,Maxime Van Landeghem,Caroline Robic,Philippe Robert,Marc Port,Denis Le Bihan,Mathieu Pernot,Mickael Tanter,Franck Lethimonnier,Sébastien Mériaux +11 more
TL;DR: The model provides an invaluable basis for optimal design and delivery of nanoparticles to the brain and the maximum gap that may be safely generated between endothelial cells and the duration of opening of the BBB is studied.
Journal ArticleDOI
Optimized diffusion gradient orientation schemes for corrupted clinical DTI data sets.
TL;DR: With the proposed approach, sets of orientations responding to several corruption scenarios can be generated, which is potentially useful for imaging uncooperative patients or infants.
Journal ArticleDOI
A new paradigm for high-sensitivity 19F magnetic resonance imaging of perfluorooctylbromide.
Céline Giraudeau,Julien Flament,Benjamin Marty,Fawzi Boumezbeur,Sébastien Mériaux,Caroline Robic,Marc Port,Nicolas Tsapis,Elias Fattal,Eric Giacomini,Franck Lethimonnier,Denis Le Bihan,Julien Valette +12 more
TL;DR: The present work revisited the NMR properties of perfluorooctylbromide to derive a high‐sensitivity fluorine MRI strategy and shows that the harmful effects of J‐coupling can be eliminated by carefully choosing the bandwidth of the 180° pulses in a spin‐echo sequence.
Journal ArticleDOI
Magnetosomes, biogenic magnetic nanomaterials for brain molecular imaging with 17.2 T MRI scanner.
Sébastien Mériaux,Marianne Boucher,Benjamin Marty,Yoann Lalatonne,Sandra Prévéral,Laurence Motte,Christopher T. Lefèvre,Françoise Geffroy,Franck Lethimonnier,Michel Pean,Daniel Garcia,Géraldine Adryanczyk-Perrier,David Pignol,Nicolas Ginet +13 more
TL;DR: Preclinical studies of human pathologies in animal models will benefit from the combination of high magnetic field MRI with sensitive, low dose, easy‐to‐produce biocompatible contrast agents derived from bacterial magnetosomes.
