Autor: Moritz C. Berger, Christine Gnahm, Nadia Benkhedah, Kristian Rink, Jonathan M. Lommen, Armin M. Nagel, Peter Bachert, Nicolas G.R. Behl, Mark E. Ladd, Vanessa Stahl

Publikováno v: Magnetic Resonance Imaging. 37:147-158

The purpose of this study is to improve direct phosphorus (31P) MR imaging. Therefore, 3D density-adapted radially-sampled balanced steady-state free precession (bSSFP) sequences were developed and an iterative approach exploiting additional anatomic

Autor: Moritz C. Berger, Peter Bachert, Armin M. Nagel, Jens Gröbner

Publikováno v: Magnetic Resonance Imaging. 34:864-874

This study aims to quantify the mean change of the effective transverse relaxation time T2(⁎) in active brain regions of human volunteers at field strengths of B0=3T and 7T. Besides the mono-exponential signal decay model an extended model is teste

Different roads to the same destination – The impact of impulsivity on decision-making processes under risk within a rewarding context in a healthy male sample

Autor: Sven Barnow, Moritz C. Berger, Frauke Nees, Rosalux Falquez, Ramona Dinu-Biringer

Publikováno v: Psychiatry Research: Neuroimaging. 248:12-22

The results of research about the influences of impulsivity on decision-making in situations of risk have been inconsistent. In this study, we used functional magnetic resonance imaging to examine the neural correlates of decision-making under risk i

Nuclear-Overhauser-enhanced MR imaging of 31P-containing metabolites: multipoint-Dixon vs. frequency-selective excitation

Autor: Peter Bachert, Mathies Breithaupt, Armin M. Nagel, Kristian Rink, Moritz C. Berger, Andreas Korzowski, Armin Biller

Publikováno v: Magnetic Resonance Imaging. 33:1281-1289

The purpose of this study is to develop nuclear-Overhauser-enhanced (NOE) [(1)H]-(31)P magnetic resonance imaging (MRI) based on 3D fully-balanced steady-state free precession (fbSSFP). Therefore, two implementations of a 3D fbSSFP sequence are compa

Publikováno v: NeuroImage. 112:353-363

The concentration of sodium is a functional cell parameter and absolute quantification can be interesting for diagnostical purposes. The accuracy of sodium magnetic resonance imaging ((23)Na-MRI) is strongly biased by partial volume effects (PVEs). H
