Relaxation Enhancement by Longitudinal Multispin Orders
نویسندگان
چکیده
Introduction: There is a great interest in increasing the longitudinal relaxation of nuclear spins for hyperpolarized imaging experiments. Longitudinal multispin orders (LOMO) correspond to the non-equilibrium population distribution and can be created in spin systems that exhibit J couplings, dipolar couplings or quadrupolar couplings (1). It can also be created via cross-correlated relaxation between different relaxation pathways present for the given spin system (2). Here we demonstrate the enhanced relaxation characteristics of 2-LOMO in weakly (AX) and strongly (AB) coupled spin systems.

Direct-product formalism for calculating magnetic resonance signals in many-body systems of interacting spins
Modern applications of nuclear magnetic resonance and electron spin resonance, and especially quantum computing problems call for more effective formalisms to describe relaxation and evolution of various orders of coherence in the presence of motions of the interacting spins. Here we suggest a formulation for the description of multiquantum spin states based on direct-product structures that ta...
متن کاملRelevance between MRI longitudinal relaxation rate and gadolinium concentration in Gd3+/GO/alginate nanocomposite
Objective(s): Relevance between magnetic resonance imaging (MRI) relaxation rate and concentration of magnetic nanoparticles determines the capability of a nanomaterial to provide MRI contrast. In the present study, alginate was conjugated to gadolinium/graphene oxide nanocomposite to form gadolinium/graphene oxide/alginate nanocomposite, aiming to investigate its effect on the relevance betwee...
متن کاملReorientations Mediated by Translational Displacements in Confined Liquid Crystals Studied by Field Cycling NMR Relaxometry and Monte Carlo Simulations
Ordering effects and low-frequency molecular dynamics in the nematic liquid crystals confined in mesoscopic pores was studied with the help of field cycling (FC) Nuclear Magnetic Resonance (NMR) relaxometry and Monte Carlo simulations. Proton relaxation rates were measured above the bulk isotropisation temperature in the broad frequency range between 2 kHz and 7 MHz. The average pore radii of c...
متن کاملScavenging free radicals to preserve enhancement and extend relaxation times in NMR using dynamic nuclear polarization.
Dynamic nuclear polarization (DNP) can enhance the nuclear polarization, that is the difference between the populations of the Zeeman levels jai and jbi of spin I= 1/2, by up to four orders of magnitude with respect to their Boltzmann distribution at room temperature. This enhancement arises from thermal mixing, which is brought about by microwave saturation of the EPR transitions of stable rad...
متن کاملThe change of longitudinal relaxation rate in oxygen enhanced pulmonary MRI depends on age and BMI but not diffusing capacity of carbon monoxide in healthy never-smokers
OBJECTIVE Oxygen enhanced pulmonary MRI is a promising modality for functional lung studies and has been applied to a wide range of pulmonary conditions. The purpose of this study was to characterize the oxygen enhancement effect in the lungs of healthy, never-smokers, in light of a previously established relationship between oxygen enhancement and diffusing capacity of carbon monoxide in the l...
