A human cerebral and cerebellar 8-channel transceive RF dipole coil array at 7T
Rolf Gruetter, Özlem Ipek, Jérémie Daniel Clément
PURPOSE: Dipole antennas that provide high transmit field penetration with large coverage, and their use in a parallel transmit setup, may be advantageous in minimizing B 1+ -field inhomogeneities at ultra-high field, i.e 7T. We have developed and evaluate ...
2019Cerebral Gray and White Matter Involvement in Anorexia Nervosa Evaluated by T1, T2, and T2*Mapping
Tobias Kober, François Lazeyras, Nurten Ceren Askin
BACKGROUND AND PURPOSE Changes in the brain composition of anorexics could potentially be expected, opening the door to new imaging approaches where quantitative and qualitative MRI have a role. Our purpose was to investigate anorexia-related brain dehydra ...
WILEY2019A 1D computer model of the arterial circulation in horses: An important resource for studying global interactions between heart and vessels under normal and pathological conditions
Nikolaos Stergiopoulos, Patrick Segers
Arterial rupture in horses has been observed during exercise, after phenylephrine administration or during parturition (uterine artery). In human pathophysiological research, the use of computer models for studying arterial hemodynamics and understanding n ...
20193D phase contrast MRI: Partial volume correction for robust blood flow quantification in small intracranial vessels
Mohamed Farhat, Pierre Bouillot
Purpose: Recent advances in 3D-PCMRI (phase contrast MRI) sequences allow for measuring the complex hemodynamics in cerebral arteries. However, the small size of these vessels vs spatial resolution can lead to non-negligible partial volume artifacts, which ...
2018Structural and functional brain imaging using extended-focus optical coherence tomography and microscopy
Neuroimaging techniques aim at revealing the anatomy and functional organisation of cerebral structures. Over the past decades, functional magnetic resonance imaging (fMRI) has revolutionized our understanding of human cerebral physiology through its abili ...
EPFL2018Hypertonic Lactate to Improve Cerebral Perfusion and Glucose Availability After Acute Brain Injury
Pierre Magistretti, Jocelyne Bloch
Objectives: Lactate promotes cerebral blood flow and is an efficient substrate for the brain, particularly at times of glucose shortage. Hypertonic lactate is neuroprotective after experimental brain injury; however, human data are limited. Design: Prospec ...
LIPPINCOTT WILLIAMS & WILKINS2018Brain Perfusion Measurements Using Multidelay Arterial Spin-Labeling Are Systematically Biased by the Number of Delays
Dimitri Nestor Alice Van De Ville, Nicolas Gninenko, Merel Margaretha van der Thiel
BACKGROUND AND PURPOSE:Multidelay arterial spin-labeling is a promising emerging method in clinical practice. The effect of imaging parameters in multidelay arterial spin-labeling on estimated cerebral blood flow measurements remains unknown. We directly c ...
AMER SOC NEURORADIOLOGY2018In vivo (13)C MRS in the mouse brain at 14.1 Tesla and metabolic flux quantification under infusion of [1,6-(13)C2]glucose
Rolf Gruetter, Cristina Ramona Cudalbu, Bernard Lanz, Carole Poitry-Yamate, Marta Lai, Corina Mihaela Berset
In vivo (13)C magnetic resonance spectroscopy (MRS) enables the investigation of cerebral metabolic compartmentation while, e.g. infusing (13)C-labeled glucose. Metabolic flux analysis of (13)C turnover previously yielded quantitative information of glutam ...
2018In vivo neurochemical measurements in cerebral tissues using a droplet-based monitoring system
Philippe Renaud, Bernard Schneider, Arnaud Bertsch, Philippe Colin, Aurélien Thomas
Direct collection of extracellular fluid (ECF) plays a central role in the monitoring of neurological disorders. Current approaches using microdialysis catheters are however drastically limited in term of temporal resolution. Here we show a functional in v ...
