Three-dimensional Volumetric Ultrasonography of Enlarged Adrenal Gland in Dog

Objective: Detection and evaluation of adrenal glands are complex problems in conventional ultrasonography in dogs. Using three-dimensional (3D) ultrasonography (US) in adrenal gland volume evaluation can add new potential for further adrenal studies. Design: Descriptive study Animals: a total of 10 mix breed dogs Procedures: The dogs underwent two dimensional (2D) and 3D US of the adrenal glands before and after 10 days of tetracosactide administration. Results: The adrenal glands increased progressively in size and volume over time which was quite significant in compare with the imitate measurements and it was detectable more in 3D US than 2D. Conclusion and Clinical Relevance: The differential diagnosis of adrenal enlargement should include PDH and adrenal tumors which apparently cannot be diagnosed by 2D nor 3D US but in detection of mild enlargements, 3D US volumetric evaluation can make a better and more accurate role than 2D
