Os animais pequenos são
muitas vezes acometidos por doenças que também necessitam de exames de imagem
complementares para auxiliar no seu diagnóstico. Hamsters, ratos, cobaios –
dentre outros pequenos mamíferos – além de aves e répteis - podem ser
facilmente submetidos à ultrassonografia, um exame não invasivo e que causa pouco
estresse, um fator que deve-se evitar sempre que possível nessas espécies. Há
diversas indicações para a realização do exame:



Presença de massas abdominais
à palpação

Evidências de secreção vulvar

Aumento de volume abdominal

Suspeita de hipotonia/atonia
intestinal (cobaios)

Diagnóstico gestacional
(ratas e cobaias)

Pesquisa de folículos e ovos (aves)

Identificação sexual em espécies monomórficas

Acesso ao estatus reprodutivo

Biópsia/citologia guiadas

O exame deve ser realizado
com transdutores de alta frequência. Cuidados especiais devem ser tomados, como por exemplo a boa secagem e aquecimento do paciente após a realização do exame, a fim de evitar a hipotermia. Também a contenção adequada e a agilidade na execução são fatores que diminuem o estresse. Por vezes é necessário a sedação ou a anestesia, a fim de diminuir os riscos de trauma e estresse por contenção.&nbsp;
