The greater sensitivity of magnetic resonance spectroscopy (MRS) compared with MRI to brain abnormalities in Rasmussen's encephalitis was demonstrated in a 3-year-old boy. The patient, with symptoms, signs and morphological findings consistent with Rasmussen's encephalitis, was followed with MRI and MRS over 30 months. That metabolic changes can be disclosed by MRS before the development of symptoms or signs was demonstrated as pathological spectra were found not only in the diseased left hemisphere but also in the morphologically normal right hemisphere before any neurological disturbance of that side.
一名3岁男孩的病例显示，与磁共振成像（MRI）相比，磁共振波谱（MRS）对拉斯穆森脑炎脑异常的敏感性更高。该患者的症状、体征和形态学表现符合拉斯穆森脑炎，在30个月内接受了MRI和MRS检查。MRS能够在症状或体征出现之前揭示代谢变化，这一点得到了证实，因为在右侧半球出现任何神经功能障碍之前，不仅在患病的左侧半球，而且在形态学上正常的右侧半球都发现了病理波谱。
