This study is aim to evaluate the neurochemical characteristics of pathological tissues by 1H MRS in patient with epilepsy at 7T. In comparison to the contralateral side, lesions in focal cortical dysplasia demonstrated significantly reduced macromolecule and N-acetyl aspartate, significantly increased total choline and glycine + myo-inositol, and a distinct reduction trend of glutamate. We conclude that performing MRS at high magnetic field offered the potential to reveal novel metabolic alterations in epilepsy lesions that may help to further understand the underlying pathophysiology of the disease.
