Critical magnetic susceptibility of gadolinium.
The magnetic suspectibility of a single crystal of high-purity gadolinium has been measured in the critical region with use of ac susceptibility methods. For reduced temperatures t 10, the data are described by a simple power law of the form Z At "with an exponent y 1.22(2) and a Curie temperature T, 293.51(3) K. For reduced temperatures t +10 3, the data cannot be described by a simple power l...
متن کاملMagnetic Resonance Imaging Property of Doxorubicin-Loaded Gadolinium/13X Zeolite/Folic Acid Nanocomposite
Background: Magnetic resonance imaging (MRI) using nanostructures has been a proper method for tumor targeting purposes. Different MRI nanomaterials, targeting agents and anticancer drugs have been used for targeting of tumors. Objectives: This study aims to consider the MRI property of doxorubicin (DOX)-loaded gadolinium/13X zeolite/folic acid (Gd3+/13X/FA) nanocomposite.<br /...
متن کاملThree-dimensional gadolinium-enhanced coronary magnetic resonance angiography: initial experience.
We present our initial experience on first-pass gadolinium-enhanced coronary artery magnetic resonance angiography (MRA). Three-dimensional segmented gradient-echo sequences were developed to image coronary arteries within a single breathhold during the injection of a double-dose contrast agent. Comparisons were made between a short TR of 2.7-msec (n = 5) and a long TR of 5.0-msec (n = 3) seque...
متن کاملNew gadolinium complexes as magnetic resonance imaging--contrast agents.
We have investigated the physicochemical and paramagnetic properties of the new gadolinium complexes of N-(pyrid-2-yl-methyl)-ethylenediamine-N,N,N-triacetic acid (Gd-PEDTA) and N-tris(2-aminoethyl)amine-N,N,N,N,N,N+hexaacetic acid(Gd-TTAHA). The relaxivities as well as the thermodynamic and conditional stability constants of these complexes with respect to the physiological relevance were dete...
متن کاملGadolinium Endohedral Metallofullerenes for Future Magnetic Resonance Imaging Contrast Agents
Gadolinium endohedral metallofullerenes (EMFs) have shown the potential to become next generation magnetic resonance imaging (MRI) contrast agents due to their significantly improved efficiency and safety, as well as multi-day body retention which allows for a longer surgery and observation compared to current contrast agents. In Chapter 1, I have reviewed the development of gadolinium EMF base...
