To determine the location of hand function in the sensorimotor cortex using MR and positron emission tomography imaging studies.
Anatomic and physiological methods were used for this study. Anatomic study was based on the MR analysis of 22 subjects. The length of the sensorimotor cortex was measured in the axial and sagittal planes. Physiologic study was based on the positron emission tomography studies of 4 subjects. Each of the studies was correlated with MR.
We found that the superior genu of the central sulcus corresponds to hand function in the sensorimotor cortex. This level may prove useful for any clinical correlations or for surgery.
From this study, the hand function area in the sensorimotor cortex is easily understood with its characteristic shape in axial MR scan. The comparison of MR and positron emission tomography data clearly show anatomic correlations. This may be applied to the functional mapping of the pathologic studies in the sensorimotor cortex regions.
利用磁共振成像（MR）和正电子发射断层扫描成像研究确定感觉运动皮层中手部功能的位置。
本研究采用解剖学和生理学方法。解剖学研究基于对22名受试者的MR分析。在轴向和矢状平面测量感觉运动皮层的长度。生理学研究基于对4名受试者的正电子发射断层扫描研究。每项研究均与MR相关联。
我们发现中央沟的上膝部对应感觉运动皮层中的手部功能。这一水平可能对任何临床关联或手术都有用。
从这项研究中，感觉运动皮层中的手部功能区在轴向MR扫描中具有特征性形状，易于理解。MR和正电子发射断层扫描数据的比较清楚地显示了解剖学关联。这可应用于感觉运动皮层区域病理研究的功能图谱绘制。
