磁共振波谱分析能定量检测脑梗死患者脑组织的生化代谢。脑梗死灶周围的Lac升高,而NAA正常或轻度降低可作为判断缺血半暗带的指标;通过检测比较NAA/Cr、mI/Cr、Cho/Cr及NAA/mI比值可辅助诊断血管性痴呆及其预后的判断;检测Glx/Cr、Cho/Cr的比值可辅助诊断卒中后抑郁障碍及其治疗效果的评价;NAA、Cho可作为卒中后失语语言功能区生化、代谢的指标。
MR spectroscopy can quantitatively detect the biochemical metabolism of brain tissue in patients with cerebral infarction. Cerebral infarction around the Lac increased, while NAA normal or mild decrease can be used as an indicator of ischemic penumbra; By comparing the NAA / Cr, mI / Cr, Cho / Cr and NAA / mI ratio can be helpful in the diagnosis of blood vessels Dementia and its prognosis; detection of Glx / Cr, Cho / Cr ratio can assist in the diagnosis of post-stroke depression and evaluation of its therapeutic effect; NAA, Cho can be used as an index of post-stroke aphasia language functional areas of biochemical and metabolic.
