摘要：

背景：X射线、CT、MRI二维图像测量股骨髁间窝受投照体位、选取测量层面等影响，测量准确性较差。
目的：比较MRI影像下股骨髁间窝三维数字化模型测量值和尸体实体解剖测量值的差异，探讨基于MRI影像下三维数字化模型的准确性。
方法：对尸体膝关节标本行MRI扫描，将MRI图像导入Mimics软件对股骨髁间窝进行三维数字化重建，测量三维数字化髁间窝的相关解剖学数据，同时对尸体标本进行解剖，测量实体解剖学数据。
结果与结论：三维数字化重建髁间窝顶长度、髁间窝宽度、内外髁宽度、髁间窝指数测量值与实体解剖测量值差异无显著性意义(P > 0.05)。说明基于MRI影像下股骨髁间窝的三维数字化模型能够准确反映实体标本信息，可用于正常人股骨髁间窝的解剖学研究。

Abstract:

BACKGROUND: X-ray, CT, and MRI two-dimensional images for measurement of the intercondylar notch are limited by the projection position and selection of measurement level and the measurement accuracy is poor.
OBJECTIVE: To explore the accuracy of three-dimensional digital model based on MRI images and to compare the difference of three-dimensional digital intercondylar notch model with cadaver.
METHODS: There were 18 male cadaveric knees and 14 female cadaveric knees scanned by MRI two-dimensional images. The MRI images were imported into Mimics Software for intercondylar notch three-dimensional reconstruction, the related anatomical data which were gotten from the three-dimensional digital model named as three-dimensional reconstruction group, while the cadavers were dissected to measure anatomical data named as entity group.
RESULTS AND CONCLUSION: The measuring values had no differences between the three-dimensional reconstruction group and entity group (P > 0.05). The three-dimensional digital model based on MRI images could accurately show the entity specimens information. It could be used for anatomy research of the normal femoral intercondylar notch.
