Magnetic resonance
Nuclear Magnetic Resonance 1NMR is an experiment in which the resonance
frequencies of nuclear magnetic systems are
investigated.
NMR always employs some form of magnetic field
(usually a strong externally applied field B0)
NMR is a form of both absorption and emission
spectroscopy, in which resonant radiation is absorbed by
an ensemble of nuclei in a sample, a process causing
detectable emissions via a magnetically induced
electromotive force.
Nuclear Magnetic Resonance 2 NMR in solids, like solution-state, relies
on the behavior of nuclear spin energy
levels in a magnetic field. However, the
interactions that affect NMR spectra act
differently.
In liquids, molecules reorient and
diffuse quickly, leading to narrow
isotropic resonances.
In solids, the fixed orientation of
individual crystallites leads to a range
of resonance frequencies for
anisotropic interactions.

Variants of the circle of willis on non contrast magnetic resonance angiographyThe Circle of Willis (CoW) distributes oxygenated blood throughout the brain and represents the only major anastomosis of the brain. The study of variations in CoW is crucial for avoiding confusion of the anomalies with aneurysms, evaluating collateral pathways in the intracerebral circulation, and enhancing pre-operative planning in patients undergoing surgery at the skull base.

Synthesis and characterization of some derivatives of 1,3-Diisopropyl-4,5-dimethylimidazol-2-ylideneN-Heterocyclic carbenes are widely used in organic reactions and coordination chemistry. In the present study, 2,3-dihydro-1,3-diisopropyl-4,5-dimethylimidazol-2-ylidene (1) is reacted with diphenyl disulfide, methyl phenyl disulfide, and bis(methylsulfonyl)methane to yield target compounds 5, 6, and 7 respectively.

Summary of thesis on doctor of medicine: Research into morphological features and some special pulse sequence on brain magnetic resonance in alzheimer patientsPractical questions put forward by clinicians in the past have been researched and settled in the thesis. The AD diagnosis is completely based on clinics and the implementation of clinical tests for the diagnosis work depends on assessors’ subjectivity. Therefore, the development of MRI techniques shall help clinicians make diagnosis more quickly and objectively.
