Abstract: Objective:To establish the three-dimensional visible model of sylvian fissure based on thin layer of MR images in Chinese adult living donor and provide the anatomic basis for clinic.Methods:The brain thin layer MR scanning in 5 healthy adult volunteers were implemented,the data were inputted to 3D-Doctor software package for establishing three-dimensional visible model of Sylvian fissure.Results:The three-dimensional visualization model of sylvian fissure was successfully constructed,which could clearly showed the three-dimensional form of sylvian fissure in brain and adjacent relationship of surrounding vital structures.The model could be rotated in any direction.Conclusions:This three-dimensional visible model of the sylvian fissure can provide morphological reference in clinical practice and the basis for virtual surgery.
