RESEARCH ARTICLE Spatially Localized Two-Dimensional J-Resolved NMR Spectroscopy via Intermolecular Double- Quantum Coherences for Biological Samples
, 1371
"... Background and Purpose Magnetic resonance spectroscopy (MRS) constitutes a mainstream technique for charac-terizing biological samples. Benefiting from the separation of chemical shifts and J cou-plings, spatially localized two-dimensional (2D) J-resolved spectroscopy (JPRESS) shows better identific ..."

. In this paper, we investigated the implementation of the localized 2D J-resolved spectroscopy based on intermolecular dou-ble-quantum coherences (iDQCs) on a 7 T MRI scanner. Materials and Methods A γ-aminobutyric acid (GABA) aqueous solution, an intact pig brain tissue, and a whole fish (Harpadon nehereus

"... The personalized approach in cancer treatment stimulates the search for new analytical techniques, including spectroscopic methods such as Raman spectroscopy, mass spectrometry MALDI (matrix-assisted laser desorption/ion-ization) imaging and high-resolution magic angle spinning nuclear magnetic reso ..."

of this method is described for breast can-cer tissues. In the near future HR MAS NMR in vitro studies of metabolic profiles combined with in vivo studies using MRI scanners may be applied as a new diag-nostic tool. Key words: tumor, metabolic profile, nuclear magnetic resonance, MALDI MS imaging, Raman
Moisture movement and thickness swelling in oriented strandboard, part 1. Analysis using nuclear magnetic resonance microimaging. Wood Sci
, 2004
"... Abstract The previous paper in this series demonstrates the use of a nuclear magnetic resonance (NMR) micro-imaging system to observe the movement of liquid water through small specimens (11 · 16 mm 2 cross-section) of oriented strandboard (OSB) and solid wood. In the present paper, a NMR body scan ..."

A VISION FOR THE FUTURE
"... Early in his medical training, Damadian chose internal medi-cine because of its analytical nature. By the time he graduat-ed, he decided to do his detective work in the research labora-tory rather than the clinic because of the prospects that his research, if successful, might help millions of peopl ..."

Whole-Body NMR Scanner (1969) and the First to Construct It (1977) The first step across the vast terrain to be traversed from the practice of clinical medicine to the physics of NMR before the new medical scanner envisioned by Damadian could become a reality came in 1969, four years before Lauterbur’s
Nuclear magnetic resonance imaging of the orbit
- Br J Ophthalmol
, 1983
"... SUMMARY Nuclear magnetic resonance is a noninvasive imaging technique which does not employ ionising radiations. The authors report its application to imaging and tissue characterisation in the normal orbit. The application of x-ray computed tomography (CT) to the investigation of orbital disease ha ..."

scanners involve substantial radiation to the eye, which cannot be avoided by screening. The radiation dose, while lower than that of comparable techniques, is still considerable,4 and recent studies indicate that, with repeated examinations a cataractogenic dose is easily reached.' Nuclear magnetic
Conductor Geometry and Capacitor Quality for Performance Optimization of Low-Frequency Birdcage Coils
"... ABSTRACT: Birdcage coils are used widely in nuclear magnetic resonance (NMR) applica-tions for their ability to operate in transmit/receive mode with high signal-to-noise ratio (SNR) and wide field homogeneity. When used at low frequencies, a number of drawbacks arise that drastically reduce their o ..."

Environment-responsive Nanophores for Therapy and Treatment Monitoring via Molecular MRI Quenching
"... The effective delivery of therapeutics to disease sites significantly contributes to drug efficacy, toxicity and clearance. Here we demonstrate that clinically approved iron oxide nanoparticles (Ferumoxytol) can be utilized to carry one or multiple drugs. These so called ‘nanophores ’ retain their c ..."

"... Magnetic resonance imaging (MRI) has significantly enhanced clinical diagnosis of disease due to a number of advantages, such as high resolution, rich information content that can be derived from a single scan, its non-invasive nature, no limitation on tissue penetration depth and the lack of radiat ..."

of radiation burden that is often encountered when other imaging modalities are utilised. In recent years 19 F MRI has gained renewed attention as an increasingly important MRI technique, mainly due to the commercial availability of high field scanners (up to 16.4 T in the preclinical setting). 19 F has
CLINICAL SCIENCES Positron Emission Tomography in Aging and Dementia: Effect of Cerebral Atrophy
"... The spatial resolution of current positron emission tomography (PET) scanners does not allow a distinction between cerebrospinal fluid (CSF) containing spaces and contiguous brain tissue. Data analysis strategies which therefore purport to quantify cerebral metabolism per unit mass brain tissue are ..."
