摘　　要：目的测量正常儿童垂体体积及各径线的值,为各种导致垂体结构改变疾病的临床诊断和科学研究提供基础数据。方法对99例自愿者儿童依次采用MRI三维快速扰相梯度回波T1(3DT1WI FSPGR)序列进行扫描,垂体的体积及各方向径线测量使用MIP和Reformat处理软件的图像。相同性别不同年龄组的比较采用方差分析,不同性别相同组别的比较采用独立样本t检验分析,垂体分型数据采用卡方分析。结果垂体体积在相同性别不同年龄组间存在显著性差异(P<0.05);不同性别相同年龄组间分型有显著性差异(P<0.05)。结论采用高分辨率MRI获得正常人儿童不同年龄段的垂体体积及多方向径线数据,为进一步研究垂体相关疾病提供了基础性数据。Objective To measure the volume and size of pituitary glands in healthy children and provide database for researching on a variety of diseases associated with alteration of pituitary structure. Methods Ninety-nine participator children were scanned by MRI using T1 weighted three-dimensional magnetization fast gradient recalled echo sequence. The volume and size of pituitary were measured using post-processing images by MIP and Reformat. The difference among three groups of same sexualities and different ages were compared by one-way ANOVA; difference between male and female were analyzed by the two-sample t-test, and the difference among measurements of the types of pituitary glands were analyzed by Chi-square test. Results The volume of pituitary among different ages has difference significance in male and female （ P 〈0.05）. The typing was more bigger than another （ P 〈0.05）. Conclusion With higher solution MRI and 3D volumetric analytic software,volume and size of pituitary glands were accurately measured so as to provide the basic data for research of the Pituitary.
