Metabolic Assessment of Myositis with 1H Magnetic Resonance Spectroscopy

Introduction Myositis is a general term used to define the inflammation of muscles. In the acute forms of myositis, this inflammation is caused by trauma, infection, certain drugs and even exercise. The chronic and sometimes progressive form of myositis is a rare condition that affects 10 in one million people each year. There has been considerable research into the pathological conditions of t...

1H magnetic resonance spectroscopy in preclinical Huntington disease.

Huntington disease (HD) is a hereditary brain disease, causing progressive deterioration after a preclinical phase. The pathophysiology of early brain abnormalities around disease onset is largely unknown. Some preclinical mutation carriers (PMC) show structural or metabolic changes on brain imaging but the most sensitive imaging modality has not been determined. (1)H magnetic resonance spectro...

The use of 1H-magnetic resonance spectroscopy in studying radiation-induced injury of the brain in elderly and young patients with nasopharyngeal carcinoma

Background: This study aims to investigate the metabolic characteristics of radiotherapy-induced temporal lobe injury in elderly patients with nasopharyngeal carcinoma using 1H-magnetic resonance spectroscopy (MRS). Materials and Methods: Data were collected from 21 elderly patients and 33 young patients before and during therapy with different radiation dosages (2...

the importance of shimming in magnetic resonance spectroscopy

conclusions by a simple check of the water peak characteristics, lots of information can be obtained, one of which is the status of shimming that has a considerable effect on the accuracy of the spectrum. thus, performing an automatic or manual shimming is not a criterion of the spectrum accuracy, and performing a periodic quality control using a test phantom by a specialist is necessary. brief...

Quantitative In Vivo Magnetic Resonance Spectroscopy Using Synthetic Signal Injection

Accurate conversion of magnetic resonance spectra to quantitative units of concentration generally requires compensation for differences in coil loading conditions, the gains of the various receiver amplifiers, and rescaling that occurs during post-processing manipulations. This can be efficiently achieved by injecting a precalibrated, artificial reference signal, or pseudo-signal into the data...
