标题
Longitudinal and transverse relaxation times of multicomponent nanoparticle (NP) chains are investigated for their potential use as multifunctional imaging agents in magnetic resonance imaging (MRI). Gold NPs (ca. 5 nm) are arranged linearly along double?

Labeling of cells with superparamagnetic iron oxide nanoparticles permits cell tracking by 1H MRI while 31P MRS allows non?invasive evaluation of cellular bioenergetics.
出版机构：John Wiley & Sons, Ltd. 刊物名称：NMR in Biomedicine 出版时间：2010 ISSN：0952-3480 数据源：报刊文摘
Maghemite particles are used as T2 contrast agents for magnetic resonance imaging, especially for molecular and cellular imaging. Linear clusters of particles ? called nanoworms ? were recently developed to enhance the targeting efficiency.

Dynamic nuclear polarization (DNP) is an NMR-based technique which enables detection and spectral characterization of endogenous and exogenous paramagnetic substances measured via transfer of polarization from the saturated unpaired electron spin system to the NMR active nuclei. 出版机构：Elsevier Science 刊物名称：Journal of Magnetic Resonance 出版时间：2010 ISSN：1090-7807 数据源：报刊文摘
Novel glass capillary array phantom: Photographic and optical microscope images of a dry water, d-PFG MRI of the constructed phantom, and the corresponding average pore diameter map calculated from d-PFG filtered MRI experiments. 出版机构：Elsevier Science 刊物名称：Journal of Magnetic Resonance 出版时间：2011 ISSN：1090-7807 数据源：报刊文摘
The 129Xe nuclear spin polarization (P Xe) that can be achieved via spin-exchange optical pumping (SEOP) is typically limited at high in-cell xenon densities ([Xe]cell), due primarily to corresponding reductions in the alkali metal electron spin polarization (e.g. 出版机构：Elsevier Science 刊物名称：Journal of Magnetic Resonance 出版时间：2011 ISSN：1090-7807 数据源：报刊文摘
ingle-sided NMR sensor to produce depth profiles with microscopic spatial resolution is presented. It uses a novel permanent magnet geometry that generates a highly flat sensitive volume parallel to the scanner surface. 出版机构：Elsevier Science 刊物名称：Journal of Magnetic Resonance 出版时间：2005 ISSN：1090-7807 数据源：报刊文摘
imed at selective detection of 23Na with specific quadrupolar couplings for in vitro NMR and MRI, we present a series of quadrupolar binomial pulse sequences offering high specificity with respect to the quadrupolar couplings of the excited species. 出版机构：Elsevier Science 刊物名称：Journal of Magnetic Resonance 出版时间：2010 ISSN：1090-7807 数据源：报刊文摘
In this paper, we describe a gradient hysteresis effect that can modulate the current in gradient coils during MRI and NMR experiments. A simple pulse sequence is presented for the purpose of evaluating the resulting changes in the accumulated phase. 出版机构：Elsevier Science 刊物名称：Journal of Magnetic Resonance 出版时间：2005 ISSN：1090-7807 数据源：报刊文摘
Parametrically Enabled Relaxation FIlters with Double and multiple Inversion (PERFIDI) is an experimental NMR/MRI technique devised to analyze samples/voxels characterized by multi-exponential longitudinal relaxation. 出版机构：Elsevier Science 刊物名称：Journal of Magnetic Resonance 出版时间：2010 ISSN：1090-7807 数据源：报刊文摘
