Ultrasonographic evaluation of the adrenalglands in healthy dogs: repeatability,reproducibility, observer-dependent variability,and the effect of bodyweight, age and sex

Résumé

Adrenal length and width were determined from two-dimensional ultrasound longitudinalimages. In study 1, 540 measurements of adrenal glands were attempted from five healthybeagle dogs by three different observers with different levels of expertise in ultrasonography,to determine the variability of adrenal gland measurements. Of these, 484 measurementswere included in the statistical analysis, since 16 measurements of the left adrenal glandand 40 for the right could not be visualised by the observer. In study 2, a single measurementof both adrenal glands was taken from each of 146 dogs by the most trained observer fromstudy 1, and the effects of different health status (healthy dogs v dogs with non-adrenaldiseases), bodyweight, age and sex were assessed. A total of 267 measurements wereincluded in the statistical analysis. The lowest intra- and inter-day coefficient of variationvalues were observed for the left adrenal gland and by the most trained observer. The healthstatus had no statistically significant effect on adrenal gland length or width, whereas agehad a significant effect only for the left adrenal gland (the greater the age, the greater thewidth or length) and sex had a significant effect only for the right adrenal gland (the widthwas larger in males and the length larger in females). The bodyweight had a significant effectfor 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 thewidth of the left adrenal gland were not statistically significant between the three observers,whereas they were statistically significant for the right adrenal gland.
