Functionalized Gold Nanoparticles as Contrast Agents for Proton and Dual Proton/Fluorine MRI

Nanomaterials, 2019
Gold nanoparticles carrying fluorinated ligands in their monolayer are, by themselves, contrast agents for 19F magnetic resonance imaging displaying high sensitivity because of the high density of fluorine nuclei achievable by grafting suitable ligands ...

Primer on gadolinium chemistry [PDF]

Journal of Magnetic Resonance Imaging, 2009
Abstract Gadolinium is widely known by all practitioners of magnetic resonance imaging (MRI) but few appreciate the basic solution chemistry of this trivalent lanthanide ion. Given the recent linkage between gadolinium contrast agents and nephrogenic systemic fibrosis, some basic chemistry of this ion must be more widely understood ...

Biodistribution of gadolinium‐based contrast agents, including gadolinium deposition [PDF]

Journal of Magnetic Resonance Imaging, 2009
AbstractThe biodistribution of approved gadolinium (Gd)‐based contrast agents (GBCAs) is reviewed. After intravenous injection GBCAs distribute in the blood and the extracellular space and transiently through the excretory organs. Preclinical animal studies and the available clinical literature indicate that all these compounds are excreted intact ...

A gadolinium cryptate with two coordinated water molecules

, 1998
An X-ray crystallographic structure determination of the nitrate salt of the gadolinium imBT cryptate shows coordination of two water molecules; NMRD relaxometry of this cryptate reveals a relaxivity of 5.8 mM–1 s–1 (at 10 MHz, 298 K and pH 6), which is ...
