Oxygen-17 NMR study of water exchange on gadolinium polyaminopolyacetates [Gd(DTPA)(H2O)]2- and [Gd(DOTA)(H2O)]- related to NMR imaging
TL;DR: In this article, the water exchange rate constants for the [Gd(DTPA)(H[sub 2]O)][sup 2[minus]] and [gd(DOTA)(H [sub 2][O]O]][sup [minus]] complexes were determined by variable-temperature [sup 17]O NMR.

Water exchange on [Gd(H2O)8]3+ and [Gd(PDTA)(H2O)2]‐ in aqueous solution: A variable‐pressure, ‐temperature and ‐magnetic field 17O NMR study
TL;DR: In this paper, the transverse and tranverse relaxation rates and chemical shifts were measured at variable temperature at three magnetic fields (1.4, 4.7 and 9.4 T) for aqueous solutions of the complexes [Gd(H2O)8]3+ and [gd(PDTA)(H 2O)2]−.
Journal ArticleDOI
Magnetic‐Field‐Dependent Electronic Relaxation of Gd3+ in Aqueous Solutions of the Complexes [Gd(H2O)8]3+, [Gd(propane‐1,3‐diamine‐N,N,N′,N′‐tetraacetate)(H2O)2]−, and [Gd(N,N′‐bis[(N‐methylcarbamoyl)methyl]‐3‐azapentane‐1,5‐diamine‐3,N,N′‐triacetate)(H2O)] of interest in magnetic‐resonance imaging

TL;DR: In this paper, the magnetic-field dependence of the transverse and longitudinal relaxation matrices for an 8S ion with such an interaction has been calculated using Redfield theory with vector-coupling methods, and diagonalised numerically to obtain relaxation rates and intensities for the degenerate transitions which contribute to the multiplet.
Book ChapterDOI
Kinetic Stabilities of Gadolinium(III) Chelates Used as MRI Contrast Agents
TL;DR: The results of the kinetic studies point to the proton, Cu2+ and Zn2+ assisted dissociation of Gd3+ complexes being slow at pH > 5.5, which indicates that the system is far from the equilibrium and the extent of in vivo dissociation is very low.
