theoretical investigations on the characteristics of the nuclear quadrupole resonance and the influence of the magnetic effect on it have been carried out. the magnetic dipole effect on the quadrupole resonance for the two spins i and i with different values oft) and e has been studied. the energy levels and their transition probabilities are presented with their corresponding spectra. the firs...

Background and Aim: Topography of the human insula has occasionally been studied in different populations. The purpose of this study was to evaluate the morphology of human insula in Iranian population and its relationship with sex, age, and handedness via magnetic resonance imaging. Methods and Materials/Patients: In our study, 380 normal magnetic resonance imaging were enrolled. The number...

This brief data article summarizes the clinical risk factors and laboratory data of a group of subjects recruited for the AIM-HIGH trial (Atherothrombosis Intervention in Metabolic Syndrome with Low HDL/High Triglycerides and Impact on Global Health Outcomes) and an associated magnetic resonance imaging (MRI) substudy. The sample is restricted to those on statin therapy at the time of enrollmen...

We have carried out precision magnetic measurements utilizing a magnetic-resonance technique, aiming for improving the magnetic-field standard below 100 mT. The standard for measuring dc magnetic flux density is intended to cover the range from 10 mT to 100 mT, with an uncertainty (k = 2) ranging from 4 mT/T to 10 mT/T.

One of the greatest challenges in developing therapeutic regimens is the inability to rapidly and objectively assess tumor response due to treatment. Moreover, tumor response to therapeutic intervention in many cases is transient, and progressive alterations within the tumor may mask the effectiveness of an initially successful therapy. The ability to detect these changes as they occur would al...

Solid-state nuclear magnetic resonance (NMR) spectroscopy has long been established as offering unique atomic-scale and element-specific insight into the structure, disorder, and dynamics of materials. NMR spectra of quadrupolar nuclei (I > (1)/2) are often perceived as being challenging to acquire and to interpret because of the presence of anisotropic broadening arising from the interaction o...

Stroke-like migraine attacks after radiation therapy syndrome is a late complication of cranial radiation. It typically presents as reversible, unilateral cortical signs and symptoms such as confusion, hemiparesis, seizures, and headaches. Magnetic resonance imaging is also required for diagnosis, demonstrating cortical linear gadolinium enhancement. Typically, these magnetic resonance imaging ...

Restorative cell-based therapies for experimental brain injury, such as stroke and traumatic brain injury, substantially improve functional outcome. We discuss and review state of the art magnetic resonance imaging methodologies and their applications related to cell-based treatment after brain injury. We focus on the potential of magnetic resonance imaging technique and its associated challeng...

Two dogs with generalized seizures were evaluated. The dogs were diagnosed with traumatic intracranial hemorrhages based on the history, neurological examinations, and magnetic resonance imaging (MRI) of the brain. Treatment was started with oxygen, prednisolone and anticonvulsant agents. No further seizure activity was observed after treatment in both dogs, however cushing reflex was detected ...
