Avaliação da ecogenicidade e ecotextura de tecidos moles da cavidade abdominal de Pets por meio da técnico de histograma em escala cinza

Abstract

Ultrasound is an imaging technique used in veterinary medicine to evaluate different organs and tissues. It is a non-invasive, safe, and cost-effective procedure that enables real-time visualization, making it valuable for assessing organs and monitoring potential pathologies. However, certain challenges are encountered in this practice, either due to reliance on the operational aspects of the equipment or the need for proper interpretation by the operator. This reliance is linked to the necessity of comparing the echogenic characteristics of organs with similar features. To address these limitations, this study aimed to correlate the qualitative and quantitative evaluation of the echogenicity and echotexture of soft tissues in the abdominal cavity of animals using the grayscale histogram (HEC) technique. For this purpose, abdominal ultrasounds of 16 different dogs were analyzed as part of the clinical routine of a veterinarian. All images were examined following a standardized measurement protocol. Subsequently, histograms with superimposed curves were created for organs with multiple ultrasound images, compiling them into a single graph for each organ of each animal. The images studied were qualitatively classified according to the condition of the organ. The grayscale histogram technique proved to be effective, demonstrating consistency between quantitative and qualitative analyses in assessing the echogenicity and echotexture of soft tissues in the abdominal cavity of animals. This method enables a more precise and objective diagnostic report while also presenting numerical patterns that can assist in the characterization and conclusion of such reports.
