Assessment Of Cerebral Osmotic Regulation In A Rat Model Of Biliary Cirrhosis Using MR Spectroscopy

Nicolas Kunz, Rolf Gruetter, Yohan Van de Looij, Cristina Ramona Cudalbu

Elsevier2012

Diffusion Tensor Echo Planar Imaging Using Surface Coil Transceiver with a Semiadiabatic RF Pulse Sequence at 14.1T

Nicolas Kunz, Rolf Gruetter, Yohan Van de Looij

Diffusion magnetic resonance studies of the brain are typically performed using volume coils. Although in human brain this leads to a near optimal filling factor, studies of rodent brain must contend with the fact that only a fraction of the head volume ca ...

Wiley-Blackwell2011

Impact of the prior knowledge on the quantification of in vivo 13C spectra using two different algorithms: LCModel and AMARES

Nicolas Kunz, Bernard Lanz, Rolf Gruetter, João Miguel das Neves Duarte, Cristina Ramona Cudalbu

2011

Hindered or restricted predominance of the diffusion weighted signal function of the diffusion time at ultra-high magnetic field

Nicolas Kunz, Rolf Gruetter, Yohan Van de Looij

2011

Developmental and metabolic brain alterations in rats exposed to bisphenol A during gestation and lactation

Nicolas Kunz, Rolf Gruetter

In recent years, considerable research has focused on the biological effect of endocrine-disrupting chemicals. Bisphenol A (BPA) has been implicated as an endocrine-disrupting chemical (EDC) due to its ability to mimic the action of endogenous estrogenic h ...

Elsevier2011

Effects of diffusion time on diffusion tensor derived parameters measured on the rat brain at ultrahigh magnetic field

Nicolas Kunz, Rolf Gruetter, Yohan Van de Looij

2010

Biophysical Basis of the Diffusion-Weighted Magnetic Resonance Signal in the Rat Brain

Nicolas Kunz

Nuclear magnetic resonance (NMR) can be used in-vivo in a vast array of applications, such as anatomical imaging (magnetic resonance imaging, MRI), localized chemical composition characterization (magnetic resonance spectroscopy, MRS), cellular structure a ...

Diffusion-Weighted Spectroscopy: A Novel Approach to Determine Macromolecule Resonances in Short-Echo Time H-1-MRS

Nicolas Kunz, Rolf Gruetter, Cristina Ramona Cudalbu

Quantification of short-echo time proton magnetic resonance spectroscopy results in >18 metabolite concentrations (neurochemical profile). Their quantification accuracy depends on the assessment of the contribution of macromolecule (MM) resonances, previou ...

Wiley-Blackwell2010

Acute Inflammatory Injury of Immature Cerebral White Matter Assessed by Spectroscopy at 9.4T

Nicolas Kunz, Rolf Gruetter

Lippincott, Williams & Wilkins2010

Multimodal NMR assessment of Erythropoietin as a neuroprotective agent following Hypoxia-Ischemia on P3 pup rat brain

Nicolas Kunz, Rolf Gruetter, Yohan Van de Looij

2009

Fast Bias Field Correction for 9.4 Tesla Magnetic Resonance Imaging

Murat Kunt, Jean-Philippe Thiran, Meritxell Bach Cuadra, Nicolas Kunz, Rolf Gruetter, Nathalie Just, Xavier Pena Pina

In this paper the problem of intensity inhomogeneity at high magnetic field on magnetic resonance images is addressed. Specifically, rat brain images at 9.4T acquired with a surface coil are bias corrected. We propose a low- pass frequency model that takes ...
