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 studyAnimals: 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. 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.

Objective- to assess the feasibility and reproducibility of two and three dimensional color and power Doppler imaging of the vasculature of the normal canine orbit and eye. Design- descriptive study.Animals- 10 mixed breed mature dogs (6 female & 4 male) weighing 14.9±1.89 kg.Procedures- In this method the transducer is placed on the eyelid. Ultrasonographic imaging was performed using a Voluson 730 pro Machine with a 2D linear multi frequency transducer (6-12MHz) and a D linear multi frequency transducer (5-12MHz). Results- Vessels identified a majority of the cases (>50%) in 2D and 3D color and power ultrasonography included: external ophthalmic artery (EOA), internal ophthalmic artery (IOA), long posterior artery (LPA), short posterior artery (SPA), dorsal ophthalmic vein (DOV), ventral ophthalmic vein (VOV), and ciliary artery (CA). the vessels imaged less frequently included: retinal artery and internal ophthalmic vein.Conclusion and Clinical Relevance- Reproducibility of 3D power and color Doppler was similar with 2D ultrasonography. The present study showed that 3D ultrasonography did not have any superiority to 2D in the eye vascular detection which could be because of small size and low velocity of the vessels in the organ.
