目的研究国人正常垂体腺形态。材料与方法采用1.5T超导磁共振成像系统，于MRI T1WI上，标准正中矢状位观察2 557例正常人垂体腺形态。结果平坦型，男性约为61%～72%，女性约为50%～84%；凹陷型，男性约为4%～32%，女性约为3%～46%；隆凸型，男性约为6%～35%，女性约为4%～46%。在30～40岁、50～60岁、60岁以上年龄段中，男女在形态上有显著差异。结论垂体腺的形态与年龄、性别有一定的关系。平坦型较为稳定，凹陷型随年龄增加而增加，隆凸型随年龄增加而减少。

Objective　To study the normal appearance of pituitary gland in Chinese individuals.　Materials and Methods　The appearance of pituitary gland in 2,557 normal individuals observed on T1WI in standard median sagittal plane was analyzed and classified.　Results　Based on the figure, the pituitary gland was divided into three types. (1) Flat type: 61%～72% in male and 50%～84% in female. (2) Concave type: 4%～32% in male and 3%～46% in female. (3) Convex type: 6%～35% in male and 4%～46% in female. Significant sex difference in pituitary shape was seen in each of 30～40, 50～60 and over 60 aged groups.　Conclusion　The pituitary shape bears a relationship to the age and sex. The flat type is quite stable. With increasing age, the concave type is becoming more common and the convex type less common.
