目的：描述功能性磁共振 (MR) 成像（感觉运动皮层的术前测绘）的临床有用应用，并使用已建立的生理技术验证结果。 材料和方法：对两名年龄分别为 24 岁和 38 岁的女性进行感觉运动皮层的功能性 MR 测绘。由于位于感觉运动皮层内或附近的肿瘤，两人都患有顽固性单纯性部分运动性癫痫发作。随后，他们在肿瘤切除之前接受了侵入性皮质标测——直接皮质刺激和/或感觉诱发电位记录——以定位受影响的感觉运动区域。 结果：在这两名患者中，功能性磁共振研究表明了感觉运动皮层的任务激活。在这两种情况下，利用侵入性技术进行的皮质功能标测的结果与通过功能性 MR 成像获得的结果相匹配。结论：感觉运动皮层的术前标测是功能性 MR 成像的潜在有用的临床应用。
PURPOSE: To describe a clinically useful application of functional magnetic resonance (MR) imaging-presurgical mapping of the sensory motor cortex-and to validate the results with established physiologic techniques.MATERIALS AND METHODS: Functional MR mapping of the sensory motor cortex was performed in two women, aged 24 and 38 years. Both had intractable, simple partial motor seizures due to tumors located in or near the sensory motor cortex. They subsequently underwent invasive cortical mapping-direct cortical stimulation and/or sensory-evoked-potential recording-to localize the affected sensory motor area prior to tumor resection.RESULTS: In both patients, the functional MR study demonstrated task activation of the sensory motor cortex. In both cases, results of cortical functional mapping with invasive techniques matched those obtained with functional MR imaging.CONCLUSION: Presurgical mapping of the sensory motor cortex is a potentially useful clinical application of functional MR imaging.
