Summary: | Joint diseases are relatively common in domestic animals, such as dogs. The involved inflammation produces thermal emission, which can be imaged using specific sensors that allow capturing of infrared images. Given that there have been few reports on the use of thermography in the diagnosis of inflammation associated with diseases of the hip joint in dogs, we here propose a method for identification of inflammatory foci in dogs by using infrared thermometry. The present study aimed to find non-invasive and low-cost resources that couldfacilitate a clinical diagnosis in cases withinflammation in the coxofemoral joint of dogs.To this end, we developed a system in whichthe Flir Systems TG165 thermograph is coupled to a black PVC cannula with a 30-cm focus-to-animal distance.External effects of the environment on the temperature of the animalswere compared with the body temperature as measured by a conventional thermometer.Thirty-one dogs with and without inflammation in the coxofemoral joint underwent clinical evaluation.We verified that the temperature registered by the thermograph inthe animals with joint inflammation was significantlydifferentfrom that incontrol animals without inflammation, in the lateral projection.The method showed a sensitivity of 80%, specificity of 87.5%, and accuracy of 83.87%. This standardized method of diagnosis of inflammatory foci in the coxofemoral articulation of dogs by way of thermography showed sensitivity, specificity, and satisfactory accuracy. |

Foram submetidos à avaliação clínica, 31 cães com e sem inflamação na articulação coxofemoral, onde verificou-se que a temperatura, registrada pelo termógrafo, dos animais pertencente ao grupo com inflamação na articulação apresentou diferença significativa na projeção lateral, em relação a temperatura dos animais do grupo sem doença articular, também aferida através do aparelho termográfico. O método apresentou sensibilidade de 80%, especificidade de 87,5% e precisão de 83,87%. Conclui-se que a padronização do método de diagnóstico de focos inflamatórios na articulação coxofemoral de cães pela termografia apresentou sensibilidade, especificidade e precisão satisfatória.UEL2018-08-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/2950810.5433/1679-0359.2018v39n4p1565Semina: Ciências Agrárias; Vol. 39 No. 4 (2018); 1565-1574Semina: Ciências Agrárias; v. 39 n. 4 (2018); 1565-15741679-03591676-546Xreponame:Semina.
