目的：我们的目的是阐明并进一步描述正常垂体的高度、长度、宽度、体积和形状的变化，以及在怀孕期间和产后前6个月漏斗部的宽度。材料和方法：对78例中晚期妊娠或产后妇女进行头颅MR成像，18名年龄匹配的未怀孕的对照受试者。体积测量进行了2种方式;体积1=1/2 × heightxlengthxwidth;和体积2=面积（通过轨迹球测量）xslice thickness.Results：腺体体积，高度，宽度，长度，凸度，漏斗宽度在怀孕期间增加。最高值出现在产后3天内。与志愿者相比，第1卷和第2卷的参数增幅最大（120%）。腺体高度相关性最好（r=0.94，p
Purpose: Our purpose was to clarify and further characterize the changes in height, length, width, volume, and shape in the normal pituitary gland and in width in the infundibulum during pregnancy and the first 6 months post partum.Material and Methods: Cranial MR imaging was performed in 78 women who were pregnant in the second or third trimester or who were post partum, and in 18 age-matched control subjects who were not pregnant. Volume measurements were performed in 2 ways; volume 1=1/2xheightxlengthxwidth; and volume 2=area (measured by trackball)xslice thickness.Results: Gland volume, height, width, length, and convexity, and infundibular width increased during pregnancy. The highest values were seen during the 3 days immediately post partum. When compared with volunteers, volumes 1 and 2 showed the largest increase (120%) among the parameters. Gland height showed the best correlation (r=0.94, p
