ABSTRACT
We conducted a retrospective study in presumed normal dogs to determine the adrenal gland attenuation and volume values. Multidetector computer tomography (MDCT 16) analysis of the gland was carried out in 48 adult dogs without evidence of adrenal gland disease that underwent CT examination for acute spinal injuries. The mean nonenhanced attenuation value +/- SD of the left adrenal gland was 36.0 +/- 5.3 HU (range 22.0-42.0 HU). The mean nonenhanced attenuation value +/- SD of the right gland was 34.3 +/- 7.0 HU (range 20.4-48.6HU). The mean enhanced attenuation value +/- SD were left gland 101.5 +/- 10.6HU (range 86.8-128.0 HU), and right gland 97.4 +/- 12.4 HU (range 58.9-123.6 HU). The mean CT volume +/- SD were left gland was 0.60 cm3 (range 0.20-0.95; SD 0.17), and right gland (0.55cm3, range 0.22-1.01; SD 0.19). Attenuation values and volume data were related to age, weight, and gender, using ANOVA. There was no statistically significant difference between the left and right side or in adrenal measurements, because of body weight class effects. The animal effect was the most important source of variation for all adrenal measurements. Based on our study, CT is an effective method for assessing adrenal characteristics in the dog. Normative CT data are provided to allow estimation of normal adrenal gland size and volume.
