Abstract

Purpose.To determine the quantitative echogenicity indicators (and their ratio) of the layers of stomach and small intestine wall in healthy dogs. Methods. A prospective 3-year study of 86 healthy dogs (aged 1-7 yrs) of different breeds and of both sexes. Echo homogeneity and echogenicity of the stomach and intestines wall were determined by the method of Silina, T.L., et al. (2010) in absolute values ​​of average brightness levels of ultrasound image pixels using the 8-bit scale with 256 shades of gray. Results. Quantitative echogenicity indicators of the stomach and the small intestine wall in dogs were determined. Based on the numerical values ​​characterizing echogenicity distribution in each layer of a separate structure of the digestive system, the coefficient of gastric echogenicity is determined as 1:2.4:1.1 (mucosa/submucosa/muscle layers, respectively), the coefficient of duodenum and jejunum echogenicity is determined as 1:3.5:2 and that of ileum is 1:1.8:1. Clinical significance. The echogenicity coefficient of the wall of the digestive system allows an objective assessment of the stomach and intestines wall and can serve as the basis for a quantitative assessment of echogenicity changes for various pathologies of the digestive system
