Proton magnetic resonance spectroscopy of patients with parkinsonism

Brain Research Bulletin, 2000
We studied cerebral metabolism in 82 patients with nonfamilial parkinsonism, including Parkinson's disease (PD; n = 23), progressive supranuclear palsy (PSP; n = 12), corticobasal degeneration (CBD; n = 19), multiple systemic atrophy (MSA; n = 18) and vascular parkinsonism (VP; n = 10) by using proton magnetic resonance spectroscopy ((1)H-MRS), which ...

Quantitative Proton Magnetic Resonance Spectroscopy of Childhood Adrenoleukodystrophy

Neuropediatrics, 1998
Cerebral metabolic disturbances in patients with childhood adrenoleukodystrophy (ALD) were assessed by quantitative localized proton MRS. Patient monitoring by follow-up MRS studies served to identify putative markers for disease onset and progression.

Proton Magnetic Resonance Spectroscopy of Pediatric Brain Tumors

Neurosurgery, 1992
1H magnetic resonance spectroscopy allows the regional quantitation of a number of metabolites from the brain in a noninvasive fashion. Spectra were obtained from 5 normal children and 25 children with brain tumors. Choline (Cho), N-acetylaspartate (NAA), creatine and phosphocreatine, and lactate were quantitated in the form of ratios.

Proton magnetic resonance spectroscopy study of dyskinesia patients

Movement Disorders, 2007
AbstractOral dyskinesias may occur spontaneously or be induced by medications such as antipsychotics and antidepressants. In this study, single voxel proton magnetic resonance spectroscopy was used to compare metabolite levels in the striatum for (1) 12 patients with drug‐induced tardive dyskinesia (TD), (2) 12 patients with spontaneous oral dyskinesia

Proton Magnetic Resonance Spectroscopy in Portal-Systemic Encephalopathy

Metabolic Brain Disease, 1998
Localized proton magnetic resonance spectroscopy (MRS) with short echo times provides unique information of human cerebral metabolism. Studies on patients with portal-systemic encephalopathy (PSE) have been performed to clarify the pathogenesis of this disease and to find a method which allows an objective diagnosis.

Proton Magnetic Resonance Spectroscopy: Part I

1972
Publisher Summary Proton magnetic resonance (p.m.r.) spectroscopy is regarded as the most widely used technique for the structural, configurational, and conformational analysis of carbohydrates and their derivatives. In context to instrumentation, sensitivity is often a limiting factor in p.m.r.
