In cerebral cortex neurosurgery and particularly in epilepsy surgery, the recognition of individual cortical anatomic landmarks is necessary for presurgical evaluation and planning. To overcome the classical great variability in the superficial aspect of the human cerebral cortex, we have developed an original generic description of the cerebral cortex in a three-dimensional structure. The result is a generic model matching the cortical topography of each brain regardless of inter- and intra-individual variability. In this model, sulcal roots (fundi) are separated by more or less superficial annectent gyrus, and buried by operculization during the gyrification. This original generic model of the cerebral cortex enabled us to develop a mathematical methodology for the construction of a structural representation of the cortical topography from a T1-weighted three-dimensional MR image. This program can provide automatic detection and recognition of the main cortical sulci.
在大脑皮质神经外科手术中,尤其是在癫痫手术中,识别个体皮质解剖标志对于术前评估和规划至关重要。为了克服人类大脑皮质表面外观的经典巨大变异性,我们开发了一种对大脑皮质三维结构的原始通用描述。结果是一个通用模型,它能匹配每个大脑的皮质地形,而不受个体间和个体内变异性的影响。在这个模型中,脑沟根部(底部)被或多或少浅表的连接回隔开,并在脑回形成过程中被脑盖化所覆盖。这种大脑皮质的原始通用模型使我们能够开发一种数学方法,用于从T1加权三维磁共振图像构建皮质地形的结构表示。该程序可以提供主要皮质脑沟的自动检测和识别。
