Adrenal length and width were determined from two-dimensional ultrasound longitudinal images. In study 1, 540 measurements of adrenal glands were attempted from five healthy beagle dogs by three different observers with different levels of expertise in ultrasonography, to determine the variability of adrenal gland measurements. Of these, 484 measurements were included in the statistical analysis, since 16 measurements of the left adrenal gland and 40 for the right could not be visualised by the observer. In study 2, a single measurement of both adrenal glands was taken from each of 146 dogs by the most trained observer from study 1, and the effects of different health status (healthy dogs v dogs with non-adrenal diseases), bodyweight, age and sex were assessed. A total of 267 measurements were included in the statistical analysis. The lowest intra- and inter-day coefficient of variation values were observed for the left adrenal gland and by the most trained observer. The health status had no statistically significant effect on adrenal gland length or width, whereas age had a significant effect only for the left adrenal gland (the greater the age, the greater the width or length) and sex had a significant effect only for the right adrenal gland (the width was larger in males and the length larger in females). The bodyweight had a significant effect for the length of both adrenal glands (the greater the bodyweight, the greater the length), but not the width. The differences between sd and coefficient of variation values for the width of the left adrenal gland were not statistically significant between the three observers, whereas they were statistically significant for the right adrenal gland.
从二维超声纵向图像确定肾上腺的长度和宽度。在研究 1 中，由三名不同超声专业水平的观察者对 5 只健康比格犬的肾上腺进行了 540 次测量，以确定肾上腺测量的可变性。其中，484 次测量被纳入统计分析，因为左侧肾上腺有 16 次测量和右侧肾上腺有 40 次测量无法被观察者观察到。在研究 2 中，由研究 1 中最训练有素的观察者对 146 只狗的每只肾上腺进行了单次测量，并评估了不同健康状况（健康犬与非肾上腺疾病犬）、体重、年龄和性别对肾上腺的影响。共有 267 次测量被纳入统计分析。观察到左肾上腺和最训练有素的观察者的最低日内和日间变异系数值。健康状况对肾上腺的长度或宽度没有统计学上的显著影响，而年龄仅对左侧肾上腺有显著影响（年龄越大，宽度或长度越大），性别仅对右侧肾上腺有显著影响（男性的宽度较大，女性的长度较大）。体重对两侧肾上腺的长度有显著影响（体重越大，长度越大），但对宽度没有影响。左侧肾上腺宽度的标准差和变异系数值之间的差异在三个观察者之间没有统计学意义，而在右侧肾上腺则有统计学意义。
