The sonograph showed that the urinary bladder was located in the caudal abdomen and its content was uniformly anechoic. The bladder wall had three layers: outer hyperechoic serosa, hypoechoic muscular layer and hyperechoic mucosa. The mean total wall thickness was 0.10\u2009cm. The splenic parenchyma had a homogeneous echotexture with greater echogenicity than that of the left renal cortex and liver. The borders were regular and tapered. Rugal folds were observed in the stomach when undistended. The mean gastric wall thickness was 0.28\u2009cm and five distinct layers were visible. The liver had smooth contours, and division of the hepatic lobes was not precisely visualized. The hepatic parenchyma had a homogeneous echotexture with greater echogenicity as compared to the right kidney and lesser echogenicity than that of the spleen. The gallbladder appeared as an oval or rounded structure in the transverse plane, filled with homogeneous anechogenic content; the wall was thin, regular and hyperechoic, with a mean thickness of 0.09\u2009cm. The kidneys had a lobulated appearance with renicular subunits. The mean total length of the kidneys in longitudinal plane was 6.18\u2009cm for the left and 6.27\u2009cm for the right. Each reniculus was covered by an echogenic capsule, and the medullary region was more hypoechogenic than the cortical region. In conclusion, sonographic features in most of the abdominal organs in Neotropical otters are similar to the ultrasound patterns observed in healthy dogs and cats, except for kidneys with reniculi.<\/jats:p>","DOI":"10.1111\/ahe.13009","type":"journal-article","created":{"date-parts":[[2023,12,16]],"date-time":"2023-12-16T13:19:36Z","timestamp":1702732776000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Sonographic features of abdominal organs in healthy captive Neotropical otters (<i>Lontra longicaudis<\/i>)"],"prefix":"10.1111","volume":"53","author":[{"given":"Beatriz","family":"de Esp\u00edrito\u00a0Augusti","sequence":"first","affiliation":[{"name":"Department of Veterinary Surgery and Animal Reproduction, School of Veterinary Medicine and Animal Science S\u00e3o Paulo State University (Unesp)  Botucatu Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sheila Canevese","family":"Rahal","sequence":"additional","affiliation":[{"name":"Department of Veterinary Surgery and Animal Reproduction, School of Veterinary Medicine and Animal Science S\u00e3o Paulo State University (Unesp)  Botucatu Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2852-6288","authenticated-orcid":false,"given":"Jeana Pereira","family":"da Silva","sequence":"additional","affiliation":[{"name":"Department of Veterinary Surgery and Animal Reproduction, School of Veterinary Medicine and Animal Science S\u00e3o Paulo State University (Unesp)  Botucatu Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mirian Hal\u00e1sc","family":"Vac","sequence":"additional","affiliation":[{"name":"IVI (Veterinary Institute of Image)  S\u00e3o Paulo Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rodrigo Hidalgo Friciello","family":"Teixeira","sequence":"additional","affiliation":[{"name":"Municipal Zoological Park \u201cQuinzinho de Barros  Sorocaba Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andre Luiz Mota","family":"da Costa","sequence":"additional","affiliation":[{"name":"Municipal Zoological Park \u201cQuinzinho de Barros  Sorocaba Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marcelo","family":"da Silva\u00a0Gomes","sequence":"additional","affiliation":[{"name":"Municipal Zoo of S\u00e3o Bernardo do Campo  S\u00e3o Paulo Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeniffer","family":"Novais","sequence":"additional","affiliation":[{"name":"Municipal Zoo of S\u00e3o Bernardo do Campo  S\u00e3o Paulo Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Oldemar Carvalho","family":"Junior","sequence":"additional","affiliation":[{"name":"Brazil Ekko Institute, (Florian\u00f3polis Otter Project) Florian\u00f3polis  Florian\u00f3polis Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria Jaqueline","family":"Mamprim","sequence":"additional","affiliation":[{"name":"Department of Veterinary Surgery and Animal Reproduction, School of Veterinary Medicine and Animal Science S\u00e3o Paulo State University (Unesp)  Botucatu Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,12,16]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1638\/1042\u20107260(2000)031[0473:CAOTNA]2.0.CO;2"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ocecoaman.2012.03.007"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1939\u20101676.1992.tb03154.x"},{"key":"e_1_2_10_5_1","first-page":"231","volume-title":"Mam\u00edferos do Brasil","author":"Cheida C.
