Brain maps derived intraoperatively from patients undergoing tumor resection were correlated retrospectively with magnetic resonance (MR) images with respect to the precise localization of the motor cortex in an attempt to identify useful preoperative MR imaging landmarks that correspond to functional brain regions. Superior axial T2-weighted MR images consistently localized the central sulcus, whereas parasagittal and farlateral sagittal images readily identified the rolandic (sensorimotor) cortex, as a functional unit, based on the cingulate-marginal sulcus and insula, respectively. It is therefore concluded that multiplanar MR images may serve as a useful preoperative planning aid prior to removing intrinsic brain tumors within or adjacent to the motor cortex.
对接受肿瘤切除术患者术中获得的脑图谱与磁共振(MR)图像进行回顾性关联,以确定运动皮层的精确位置,试图识别与功能性脑区相对应的术前有用MR成像标志。轴位T2加权MR图像能持续定位中央沟,而矢状旁位和远外侧矢状位图像则分别基于扣带缘沟和脑岛,轻易地将罗兰(感觉运动)皮层识别为一个功能单元。因此得出结论,在切除运动皮层内或其附近的脑内肿瘤之前,多平面MR图像可作为有用的术前规划辅助手段。
