Proton Magnetic Resonance Spectroscopy Changes After Antipsychotic Treatment

Current Medicinal Chemistry, 2013
Proton magnetic resonance spectroscopy ((1)H MRS) enables the observation of brain function in vivo. Several brain metabolites can be measured by the means of (1)H MRS: N-acetylaspartate (NAA), choline containing compounds (Cho), myo-inositol (mI) and glutamate (Glu), glutamine (Gln) and GABA (together as Glx complex or separately).

[Proton magnetic resonance spectroscopy (1H-MRS)].

No shinkei geka. Neurological surgery, 2021
Proton magnetic resonance spectroscopy(1H-MRS)is a non-invasive method for evaluating brain function and metabolism. 1H-MRS can quantify low-molecular-weight metabolites in a living brain; it shows their spectra without tracer administration. In this paper, we introduce 1H-MRS and MRS for imaging the distribution of metabolites.

Proton magnetic resonance spectroscopy during transient global amnesia

Journal of the Neurological Sciences, 1998
There is uncertainty about the etiology of transient global amnesia and none of the pathogenetic hypotheses proposed so far, i.e. transient ischemia, epileptic discharge and spreading depression of cortical electrical activity, is completely satisfactory.

Proton magnetic resonance spectroscopy in childhood brainstem lesions

Child's Nervous System, 2006
Diagnosis of brainstem lesions in children based on magnetic resonance imaging alone is a challenging problem. Magnetic resonance spectroscopy (MRS) is a noninvasive technique for spatial characterization of biochemical markers in tissues and gives information regarding cell membrane proliferation, neuronal damage, and energy metabolism.We measured the

Proton magnetic resonance spectroscopy in Creutzfeldt‐Jakob disease

Neurology, 1993
We studied two patients with Creutzfeldt-Jakob disease by in vivo proton magnetic resonance spectroscopy and obtained spectra from an extract of biopsy tissue from a third patient. In vivo spectra from the two patients, 3 months and less than 1 month after symptom onset, revealed only minor changes. A second study of one of the patients 10 months after

Proton magnetic resonance spectroscopy of brain-stem lesions

Neuroradiology, 2002
The imaging findings of brain-stem lesions are often nonspecific and histological diagnosis is limited because of fear of complications associated with biopsy. A noninvasive method for tissue characterization is therefore highly desirable. We undertook a review of proton magnetic resonance spectroscopy (MRS) of patients with solitary brain-stem lesions

Multivoxel proton magnetic resonance spectroscopy in heat stroke

Clinical Radiology, 2015
To assess the role of proton MR spectroscopy (MRS) in the detection of changes in metabolite levels of the cerebellum after heat stroke (HS).The study group consisted of eight patients after HS, with a Glasgow Coma Scale (GCS) score of 3-9. The MR studies were performed with a 1.5 T system.

Proton magnetic resonance spectroscopy in ecstasy (MDMA) users

Neuroscience Letters, 2004
The popular recreational drug 3,4-methylenedioxymethamphetamine (MDMA, ecstasy) has well-recognized neurotoxic effects upon central serotonergic systems in animal studies. In humans, the use of MDMA has been linked to cognitive problems, particularly to deficits in long-term memory and learning.

Proton magnetic resonance spectroscopy of human fetal brain

American Journal of Obstetrics and Gynecology, 1994
In vivo proton magnetic resonance spectroscopy of human fetal brain was performed in the third trimester of pregnancy. Spectra were obtained showing signals assigned to cerebral compounds such as N-acetylaspartate, creatine, and cholines. Relative signal intensities were similar to those observed in neonatal brain spectra recorded during the early ...
