摘要
为给大脑占位性病变及脑功能的影像学研究提供断层解剖学依据，利用１５ 例头部矢状断层标本及相应脑片，颅脑ＭＲＩ矢状扫描图像研究了大脑沟、回在ＭＲＩ矢状图像上的定位。结果显示：扣带沟缘支和外侧沟后升支是识别中央沟的标志，若出现壁间回则更易识别中央沟；借外侧沟前水平支和前升支形成的“Ｙ”或“Ｖ”形外观，可识别中央前沟及额下回的眶部、三角部和岛盖部；侧副沟居海马结构下方，其下方为枕颞内侧回。选了８ 个典型矢状扫描层面详细介绍大脑沟。
To provide sectional anatomic data for MRI localization of cerebral lesions and imaging study of brain function, localization of cerebral sulci and gyri on the sagittal MR imaging was investigated using 15 sets of serial sagittal sections of adult heads and MR imaging of cadaver head corresponding to brain slices. The results showed that marginal ramus of cingulate sulcus and posterior ascending ramus of lateral sulcus are the landmarks for recognition of central sulcus. If the interwall gyrus appeared, the central sulcus is recognized more easily. Precentral sulcus and orbital, triangular, and opercular parts of inferior frontal gyrus are recognized using a Y or V shaped appearence formed by the anterior horizontal and anterior ascending rami of lateral sulcus. Collateral sulcus is inferior to the hippocampal formation, its inferior gyrus is medial occipitotemporal gyrus. This paper also introduced the recognition of cerebral sulci and gyri on 8 typical sections.
