摘　　要：目的:探讨端脑额叶髓突的不对称性,为脑的功能性研究提供形态学基础。方法:随机抽取96例正常颅脑CT图像,选择典型层面进行髓突定位,观测冠状断层的端脑额叶髓突形态和面积,并用SPSS软件分析端脑的侧别和性别差异。结果:男性额中回髓突面积左>右,女性额上回髓突面积左<右,有显著性侧别差异,但均无显著性性别差异;额叶各髓突分支,均无显著性侧别差异,但额下回髓突支数具有显著性性别差异(男性<女性)。额上回髓突面积(左<右)和额中回髓突面积(左>右)有极显著侧别差异。结论:在冠状断面上额叶髓突在面积和分支上具有明显不对称性,额下回髓突的分支数具有明显性别差异。Objective： In order to study the asymmetrical characteristic of frontal cerebral medullar branches on CT imaging. methods： Were Chosen 96 normal cerebral CT images on coronal plane to observe and measure the area and branches of the frontal cerebral medullar process, and then all the data was analyzed by the software SPSS. Results： The significant difference of the area of frontal cerebral medullar process was only found in the medullar process corresponding to the middle frontal cerebral gyrus in male （left〉right）, and was found in the medullar process corresponding the superior frontal cerebral gyrus in female（left〈right）. No significant difference was found between male and female. The difference of the number of branches of the inferior frontal cerebral medullar process was significant between male and female, the number in males being less than in females. Ignoring the difference of the gender, and merging all the data there was a grestly significant difference in the superior and middle frontal cerebral medullar process on the coronal plane. Conclusions： Only a few area of frontal cerebral medullar processes were asymmetrical on the coronal plane. The difference of the numbers of branches of the inferior frontal cerebral medullar process was significant between male and female.
