Objective To understand the metabolic patterns of NAA, Cr and Cho in radiation encephalopathy (RE) induced by radiotherapy for nasopharyngeal carcinoma detected by proton magnetic resonance spectroscopy (1H-MRS), and provide useful evidence for early diagnosis of this disease.

[Objective]To investigate the application of proton magnetic resonance spectroscopy(1H-MRS) on the evaluation of the therapeutic effects of Ganzhixiao Capsule in treating nonalcoholic fatty liver disease(NAFLD).

Proton magnetic resonance spectroscopy(H-MRS) is a noninvasive method to measure biochemical metaboilic level of tissues and cells in vivo,which plays an important role in the early diagnosis and precise staging of intracranial tumor.

Objective To investigate the application of proton magnetic resonance spectroscopy (1H-MRS) in detecting the biochemical metabolism in children with febrile seizure(FS), and to evaluate the information of brain injury and study the clinical significance of 1H-MRS in FS.

Objective To investigate changes of proton magnetic resonance spectroscopy(1H MRS) in Alzheimer disease(AD) and mild cognitive impairment(MCI) in comparisonwith senior volunteers who have normal cognitive(NC).

Objective To investigate the change of proton magnetic resonance spectroscopy(~(1)H-MRS) in (patients) of Alzheimer disease(AD) and compaired with normal cognition(NC).
