The pituitary gland was measured from transverse magnetic resonance T1-weighted images after Gadolinium administration in 96 dogs weighing from 13 to 45 kg. The measurements were done by hand with calipers. The mean (+/- standard deviation) pituitary gland height was 5.1 mm (+/-0.9 mm). The mean width was 6.4 mm (+/- 1.1 mm). The correlation coefficient between pituitary and brain measurements, between pituitary measurement and body weight, and brain measurements and body weight was 0.0 to 0.3. A hyperintense region was present on T1-weighted images in the center of the pituitary gland in 64% of the dogs. At necropsy the pituitary glands were grossly and histologically normal. No pituitary gland measurements were performed at necropsy.
对96只体重在13至45千克之间的犬，在注射钆后通过横向磁共振T1加权图像测量垂体。测量使用卡尺手工进行。垂体平均高度为5.1毫米（±0.9毫米）。平均宽度为6.4毫米（±1.1毫米）。垂体与脑测量值之间、垂体测量值与体重之间以及脑测量值与体重之间的相关系数为0.0至0.3。64%的犬在垂体腺中心的T1加权图像上存在高信号区。尸检时垂体外观和组织学均正常。尸检时未进行垂体测量。
