Monitoring of Superparamagnetic Particle Sizes in the Langevin Law Regime

Autor: Yves Gossuin, Quoc Lam Vuong, Xavier Valentini, Sébastien Delangre, Maurice Gonon, Denis Nonclercq, Daniel Henrard

Publikováno v: Journal of Nanomaterials, Vol 2019 (2019)

In this work, aqueous solutions of magnetite nanoparticles (NPs) are studied. Magnetite NPs are very useful in biomedicine for magnetic resonance imaging (MRI), for drug delivery therapy, and also for hyperthermia. In order to predict the NP efficien

Improvement of the Off-Resonance Saturation, an MRI sequence for positive contrast with SPM particles: Theoretical and experimental study

Autor: Quoc Lam Vuong, Bernard Gallez, Chrystelle Po, Sébastien Delangre, Yves Gossuin

Publikováno v: Journal of Magnetic Resonance. 265:99-107

The SuperParaMagnetic particles (SPM particles) are used as contrast agents in MRI and produce negative contrast with conventional T2 or T2(∗)-weighted sequences. Unfortunately, the SPM particle detection on images acquired with such sequences is s

Bottom-up study of the MRI positive contrast created by the Off-Resonance Saturation sequence

Autor: Sébastien Delangre, Daniel Henrard, Bernard Gallez, Quoc Lam Vuong, Chrystelle Po, Yves Gossuin

Publikováno v: Journal of Magnetic Resonance. 254:98-109

Superparamagnetic iron oxide nanoparticles (SPM particles) are used in MRI to highlight regions such as tumors through negative contrast. Unfortunately, sources as air bubbles or tissues interfaces also lead to negative contrast, which complicates th

Theoretical and experimental study of ON-Resonance Saturation, an MRI sequence for positive contrast with superparamagnetic nanoparticles

Autor: Daniel Henrard, Quoc Lam Vuong, Bernard Gallez, Julie Magat, Sébastien Delangre, Chrystelle Po, Yves Gossuin

Publikováno v: Journal of magnetic resonance (San Diego, Calif. : 1997). 252

Superparamagnetic iron oxide nanoparticles (SPM particles) are widely used in MRI as negative contrast agents. Their detection is sometimes difficult because negative contrast can be caused by different artifacts. To overcome this problem, MRI protoc

New simulation approach using classical formalism to water nuclear magnetic relaxation dispersions in presence of superparamagnetic particles used as MRI contrast agents

Autor: Quoc Lam Vuong, Yves Gossuin, Sébastien Delangre, Pierre Gillis

Publikováno v: The Journal of Chemical Physics. 137:114505

Superparamagnetic nanoparticles are used as negative contrast agents in magnetic resonance imaging: owing to their large magnetic moment the water proton spins are dephased, which accelerates the nuclear magnetic relaxation of an aqueous sample conta
