【摘要】：目的·用高分辨率磁共振成像(MRI)观察正常成人脑垂体的变化规律。方法·对245例健康成年受试者采用3.0T MRI扫描,检测垂体横径、矢径、高度和体积,观察垂体的形态。结果·垂体平均高度男性为(5.47±1.33)mm,女性为(6.06±1.32)mm;垂体平均体积男性为(614.07±125.52)mm~3,女性为(660.00±117.35)mm~3。不同性别之间差异均有统计学意义(均P0.01)。垂体高度与垂体体积之间呈正相关(r=0.829,P0.01)。除垂体矢径外,不同年龄段受试者的垂体横径、高度和体积之间差异均有统计学意义(均P0.05),且均与年龄呈负相关(均P0.01)。结论·正常成人垂体高度和体积均在18~29岁最大,此后随年龄增大而减小,但女性在50~59岁垂体高度和体积会再次增大;女性垂体平均高度和体积均显著大于男性。
[Abstract]:Objective to observe the changes of pituitary gland in normal adults with high resolution magnetic resonance imaging (MRI). Methods 3. 0T MRI scanning was performed on 245 healthy adult subjects. The transverse diameter, sagittal diameter, height and volume of pituitary gland were measured and the morphology of pituitary was observed. Results the average height of pituitary gland was 5.47 卤1.33 mm in male and 6.06 卤1.32 mm in female, the mean volume of pituitary gland was 614.07 卤125.52 mm / 3 in male and 660.00 卤117.35 mm / 3 in female. There were significant differences between different genders (all P 0.01). There was a positive correlation between pituitary height and pituitary volume. Except the sagittal diameter of the pituitary gland, there were significant differences in the transverse diameter, height and volume of the pituitary gland between the subjects of different ages (all P 0.05) and negative correlation with age (all P 0.01). Conclusion the height and volume of pituitary gland in normal adults are the highest at the age of 1829, and then decrease with the increase of age, but the height and volume of the pituitary gland will increase again in the female at the age of 50 to 59 years, and the average height and volume of the pituitary gland in the female is significantly higher than that in the male.
