Optimal RF flip angles for multiple spin-echoes and iMQCs of different orders with the CRAZED pulse sequence
TLDR
In this paper, an analytical expression for the dependence of signal intensities on RF pulse flip angles was derived for the cases when higher-order expansion terms of Bessel functions can be neglected from a combination of dipolar demagnetizing field treatment and product operator formalism.About:

Observation and characterization of intermolecular homonuclear single-quantum coherences in liquid nuclear magnetic resonance
TL;DR: In this paper, the properties of homonuclear intermolecular single-quantum coherences (iSQCs) from second-order spin interactions were investigated.

Optimizing the sequence parameters for double-quantum CRAZED imaging.
José P. Marques,Richard Bowtell +1 more
TL;DR: The evolution of magnetization during repeated application of the double‐quantum‐(DQ)‐CRAZED sequence is analyzed, with the aim of identifying sequence parameters that maximize sensitivity to signal produced by the distant dipole field (DDF).
Journal ArticleDOI
Chemical exchange saturation transfer by intermolecular double-quantum coherence
TL;DR: The method was validated using clinically relevant systems based on glycosaminoglycans and a sample of cartilage tissue, showing that the CEST contrast, as well as, NOE are enhanced by iDQC.

Localized intermolecular zero-quantum coherence spectroscopy in vivo
Dávid Z. Balla,Cornelius Faber +1 more
TL;DR: In this paper, a pictorial explanation is given of how iZQC signal is formed under the action of the distant dipolar field in the sample and how this local refocusing process leads to line narrowing in the indirect dimension of 2D spectra.
Journal ArticleDOI
Functional magnetic resonance imaging with intermolecular double-quantum coherences at 3 T
TL;DR: It is hypothesized that substantial inherent diffusion weighting of the iDQC technique efficiently suppresses intravascular contributions to the functional contrast.

Generation of impossible cross-peaks between bulk water and biomolecules in solution NMR
TL;DR: These results imply that peak intensities (critical for structural determinations) can be distorted in many gradient experiments, and show that magic-angle gradients provide substantial improvements with reduced gradient strengths.

NMR multiple echoes observed in solid He 3
TL;DR: In this paper, the effect of the nuclear demagnetizing field in the equation of motion of the magnetization has been investigated in the case of multiple echoes, where a large number of echoes are observed following two isolated NMR radio-frequency pulses separated by a time.
