Harmonization of multi-scanner in vivo magnetic resonance spectroscopy: ENIGMA consortium task group considerations

Cristina Ramona Cudalbu

Magnetic resonance spectroscopy is a powerful, non-invasive, quantitative imaging technique that allows for the measurement of brain metabolites that has demonstrated utility in diagnosing and characterizing a broad range of neurological diseases. Its impa ...

Development and Optimization of Methods for Accelerated Magnetic Resonance Imaging

Tom Hilbert

Magnetic resonance imaging (MRI) has yielded great success as a medical imaging modality in the past decades, and its excellent soft tissue contrast is used in clinical routine to support diagnosis today. However, MRI is still facing challenges. For exampl ...

Evaluation of Water Exchange Kinetics on [Ln(AAZTAPh–NO2)(H2O)q]x Complexes Using Proton Nuclear Magnetic Resonance

Lothar Helm, Shima Karimi

Water exchange kinetics on [Ln(AAZTAPh–NO2)(H2O)q]− (Ln = Gd3+, Dy3+, or Tm3+) were determined by 1H nuclear magnetic resonance (NMR) measurements. The number of inner-sphere water molecules was found to change from two to one when going from Dy3+ to Tm3+. ...

Advanced magnetic resonance spectroscopy and imaging techniques applied to brain development and animal models of perinatal injury

Yohan Van de Looij

Magnetic resonance spectroscopy (MRS) and magnetic resonance imaging (MRI) are widely used in the field of brain development and perinatal brain injury. Due to technical progress the magnetic field strength (B0) of MR systems has continuously increased, fa ...

De l'usage des protons hyperpolarisés pour augmenter la sensibilité de la RMN

Aurélien Bornet

Nuclear Magnetic Resonance (NMR) has become an inescapable technique for spectroscopic identification. Its main advantage comes from the sensitivity of NMR active nuclei embedded in a molecule to their chemical environment. NMR is also used daily in medica ...

Correcting surface coil excitation inhomogeneities in single-shot SPEN MRI

Rolf Gruetter, Mor-Miri Mishkovsky, Jean-Noël Hyacinthe, Arnaud Comment, Nicolas Kunz

Given their high sensitivity and ability to limit the field of view (FOV), surface coils are often used in magnetic resonance spectroscopy (MRS) and imaging (MRI). A major downside of surface coils is their inherent radiofrequency (RF) B1 heterogeneity acr ...

Improved surface coil design and pulse sequence development for in vivo 13C MR spectroscopy of humans at 7T

Eulalia Serés Roig

Nuclear magnetic resonance (NMR) is a non-invasive tool for the study of human diseases. In particular, carbon-13 magnetic resonance spectroscopy (13C MRS) is a promising derivative tool for investigating metabolism in vivo, as it allows the non-invasive m ...
