Since contrasts agents are used in magnetic resonance imaging (MRI), numerous efforts have been done to increase their relaxivity (parameter allowing to quantify contrast agent efficiency). Few years ago, the Merbach group developed the chelating agent DTT ...
This work explores a concept for motion detection in brain MR examinations using high channel-count RF coil arrays. It applies ultrashort (< 100 mu sec) free induction decay signals, making use of the knowledge that motion induces variations in these signa ...
The search for higher spatial resolution and better sensitivity stimulates the development of high-field (3 T) and ultrahigh field (>3 T) MRI scanners. Gadolinium-based MRI contrast agents, commercial ones used in clinics, as well as recently developed mor ...
Catalase and methaemoglobin have very similar haem groups, which are both ferric, yet catalase decomposes hydrogen peroxide to water and oxygen very efficiently, while methaemoglobin does not. Structural studies have attributed this behaviour to their diff ...
We employ triple-resonance vibrational overtone excitation to access quasibound states of water from several fully characterized bound states of the molecule. Comparison of the measured dissociation spectra allows a rigorous assignment of rotational quantu ...
An Electron Paramagnetic Resonance (EPR) study of glasses and magnetically dilute powders of [Gd(DTPA)(H2O)]2−, [Gd(DOTA)(H2O)]-, and macromolecular Gd-P792 complexes was carried out at X-, Q-band and 240 GHz DTPA=diethylenetriaminepentaacetato; DOTA=1,4,7 ...
Mn2+ complexes represent an alternative to Gd3+ chelates which are widely used contrast agents in magnetic resonance imaging. In this perspective, the authors studied the Mn2+ complexes of two 12-membered, pyridine-contg. macrocyclic ligands bearing one pe ...
By shining mm-waves upon a sample containing unpaired electron spins, DNP provides a way to enhance NMR signals. We report the characterization of a universal polarizer for EM-waves at 140 GHz made by rectangular grooved mirrors as well as design considera ...
Magnetic resonance imaging contrast agents are currently designed by modifying their structural and physiochemical properties to improve relaxivity and to enhance image contrast. Here, we show a general method for increasing relaxivity by confining contras ...
A novel bis-hydroxymethyl-substituted DTTA chelator N¢-Bz-C4,4¢-(CH2OH)2-DTTA (1) and its DTPA analogue C4,4¢-(CH2OH)2-DTPA (2) were synthesized and characterized. A variable-temperature 1H NMR spectroscopy study of the solution dynamics of their diamagnet ...
