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 por cento (21/25) dos casos, mas 16 por cento (4/25) apresentaram resultado falso-negativo. O exame ultrassonográfico foi capaz de diagnosticar acertadamente 76 por cento (19/25) dos casos, e sugeriu a ruptura do LCCr nos 24 por cento (6/25) restantes, apresentando 100 por cento 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 percent (21/25) of the cases, but 16 percent (4/25) were false-negative. Ultrasonography identified accurately 76 percent (19/25) of the cases and gave a probable diagnosis for the remaining 24 percent (6/25) what means that this technique presented 100 percent of positive results. It was possible to conclude that radiography and ultrasonography are valuable tools for the diagnosis of CrCL rupture in dogs.
