Abstract

The study of the wildlife has increased because many species find themselves threatened with extinction, the Amazonian manatee (Trichechus inunguis) is classified as vulnerable. The main factors that aggravate this situation is the slow reproduction of these animals, as well as poaching, which still occurs in the Amazon region, increased the need for preservation. The study of this kind is crucial to generate knowledge about the same, contributing in an attempt to reverse your current frame. Research on diagnostic imaging for manatees are rare, especially when directed ultrasound, it is an excellent technique to be carried out in wild animals, for not being invasive and provide real time information of each body. This abdominal ultrasound research will generate normal data, in the future we can diagnose diseases. The aim of this study was to standardize the examination technique and describe the abdominal ultrasound findings in inunguis Trichechus bred in captivity, increasing knowledge about the species and consequently aid in the diagnosis of diseases. The survey was conducted with 18 animals to describe the normal sonographic anatomy in the abdominal cavity of Amazonian manatee. During abdominal scan was viewed homogeneous liver, hyperechoic contoured edges and regular; the gallbladder showed anechoic content with regular and thin wall; stomach was present gas content, hypoechoic and thin wall. In the caudal abdomen visibilizou urinary bladder in piriformis format, bit full, hyperechoic wall and content ranging from anechoic and hypoechoic. Evaluated the subcutaneous tissue, which can differentiate the layer of skin, fat, muscle and peritoneum. The ultrasound examination obtained satisfactory results in this study, concluding that an efficient technique for evaluation in Amazonian manatee
