Abstract

Radiografia e ultrassonografia foram avaliadas como técnicas no diagnóstico por imagem na ruptura do ligamento cruzado cranial (LCCr) em cães. Vinte e cinco cães foram submetidos à radiografia e ultrassonografia e seus resultados foram comparados aos obtidos por artrotomia (teste padrão ouro). O exame radiográfico diagnosticou corretamente a lesão em 84% (21/25) dos casos, mas 16% (4/25) apresentaram resultado falso-negativo. O exame ultrassonográfico foi capaz de diagnosticar acertadamente 76% (19/25) dos casos, e sugeriu a ruptura do LCCr nos 24% (6/25) restantes, apresentando 100% de resultados positivos. Concluiu-se que a radiografia e a ultrassonografia são ferramentas valiosas para diagnosticar casos de ruptura do LCCr em cães. ; Radiography and ultrasonography were evaluated as tools for diagnosis of the rupture of cranial cruciate ligament (CrCL) in dogs. Twenty-five dogs were submitted to radiographic and ultrasonographic examinations and their results were compared with those obtained by artrotomy (gold standard). Radiography detected the rupture in 84% (21/25) of the cases, but 16% (4/25) were false-negative. Ultrasonography identified accurately 76% (19/25) of the cases and gave a probable diagnosis for the remaining 24% (6/25) what means that this technique presented 100% of positive results. It was possible to conclude that radiography and ultrasonography are valuable tools for the diagnosis of CrCL rupture in dogs.
