Magnetic resonance spectroscopy (MRS) is indicated in the imaging protocol of the patient with epilepsy to screen for metabolic derangements such as inborn errors of metabolism and to characterize masses that may be equivocal on conventional magnetic resonance imaging for dysplasia versus neoplasia. Single-voxel MRS with echo time of 35 milliseconds may be used for this purpose as a quick screening tool in the epilepsy imaging protocol. MRS is useful in the evaluation of both focal and generalized epilepsy.
磁共振波谱（MRS）在癫痫患者的成像方案中是有指征的，用于筛查代谢紊乱，如先天性代谢缺陷，以及对常规磁共振成像表现为发育不良或肿瘤的可疑病变进行定性。回波时间为 35 毫秒的单体素 MRS 可作为癫痫成像方案中的快速筛查工具。MRS 在局灶性和全面性癫痫的评估中均有用。
