In this study, activation of cortical sites by specific motor tasks (opening and closing of the hand) was examined by fMRI utilizing the blood-oxygen-level-dependent (BOLD) technique. fMRI was employed in five volunteers and in six patients with tumors in the vicinity of the central region. In the patients, the fMRI data and intraoperative cortical mapping were compared. Our results indicate good correlation of these two methods and that there are no significant differences in the localization of the motor hand area.
在本研究中，利用功能磁共振成像（fMRI）的血氧水平依赖（BOLD）技术，检测了特定运动任务（手部开合）对皮质位点的激活情况。对5名志愿者和6名中央区附近有肿瘤的患者进行了fMRI检查。对患者的fMRI数据和术中皮质图谱进行了比较。我们的结果表明这两种方法具有良好的相关性，并且运动手部区域的定位没有显著差异。
