A patient with a glioblastoma multiforme and mild sensorimotor deficits had significantly less activation of the motor and sensory cortices on the side with the tumor than on the contralateral side on blood oxygen level-dependent (BOLD) functional MR images. This difference, which may be due to pressure effects or loss of vascular autoregulation, should be considered in preoperative planning in which BOLD functional MR imaging is used to identify eloquent cortices to be avoided during brain tumor surgery.
一名患有多形性胶质母细胞瘤且有轻度感觉运动功能缺损的患者，在基于血氧水平依赖（BOLD）的功能磁共振成像（MRI）上，肿瘤侧运动和感觉皮层的激活明显少于对侧。这种差异可能是由于压力效应或血管自动调节功能丧失所致，在术前规划中应予以考虑，在该规划中，BOLD功能MRI用于识别脑肿瘤手术中应避开的明确皮层。
