大脑扣带回皮层的三维重建及可视化

Three-dimensional reconstruction and visualization of cerebral cingulate cortex

摘要

摘要:
目的建立健康成人活体MR图像的大脑扣带回皮层三维可视化模型，为脑立体定向微创手术提供扣带回皮层及邻近区域解剖学模型。
方法选取1名健康成年女性颅脑薄层冠状位MR图像数据，将其导入3D-Doctor软件，并使用手工分割方法建立大脑扣带回皮层、侧脑室、大脑纵裂和大脑外表面轮廓的三维重建模型。
结果成功构建大脑扣带回皮层三维可视化图像，成功显示大脑扣带皮层、侧脑室、大脑纵裂和大脑外表面的立体结构形态及与邻近脑组织结构关系。
结论大脑扣带回皮层的三维可视化模型的构建对扣带回解剖结构的识别、脑立体定向手术设计、扣带回皮层区域病变定位诊断和功能研究有重要价值。

Abstract:
ObjectiveTo establish a three-dimensional visualization model of brain cingulate cortex in healthy adult MR image, and provide an anatomical model of cingulate cortex and adjacent structure for stereotactic minimally invasive surgery of brain.
MethodsThe MR image data of a cranial thin layer coronal plane in a healthy adult woman were imported into 3D-Doctor software, and the three-dimensional reconstruction of the cingulate cortex, lateral ventricle, cerebral longitudinal fissure and outer contour of brain were established using the manual segmentation method.
ResultsA three-dimensional visual image of the cingulate cortex of brain was successfully constructed, and could successfully show the three-dimensional structure of the cingulate cortex, lateral ventricle, cerebral longitudinal fissure and outer surface of brain, and its relationship with adjacent brain structure.
ConclusionsThe construction of three-dimensional visualization model of the cingulate cortex of brain has important value in the recognition of the anatomical structure of cingulate gyrus, design of the stereotactic surgery of brain, and positioning diagnosis and functional study of cingulate cortex area.
