This article compares resting-state functional magnetic resonance (fMR) imaging with task fMR imaging for presurgical functional mapping of the sensorimotor (SM) region. Before tumor resection, 38 patients were scanned using both methods. The SM area was anatomically defined using 2 different software tools. Overlap of anatomic regions of interest with task activation maps and resting-state networks was measured in the SM region. A paired t-test showed higher overlap between resting-state maps and anatomic references compared with task activation when using a maximal overlap criterion. Resting state-derived maps are more comprehensive than those derived from task fMR imaging.
本文比较了静息态功能磁共振（fMR）成像与任务态fMR成像在术前感觉运动（SM）区功能图谱绘制中的应用。在肿瘤切除术前，对38例患者使用这两种方法进行了扫描。使用2种不同的软件工具在解剖学上定义了SM区。在SM区测量了感兴趣的解剖区域与任务激活图和静息态网络的重叠情况。当使用最大重叠标准时，配对t检验显示静息态图与解剖学参考之间的重叠高于任务激活。静息态衍生图比任务态fMR成像衍生图更全面。
