Thermographic evaluation in equine: literature review
Keywords:
Diagnóstico por imagem, temperatura, cavalosAbstract
Thermography is a non-invasive technique, capable of directly measuring temperature, detecting the heat emitted by the target surface as infrared radiation. The thermographic image can measure skin temperature that reflects the degree of inflammation in injured tissues, and this ability makes its valid use to aid in the diagnosis and prevention of certain conditions in horses. Vascularization and blood supply are the basis of thermographic representation. The procedure is non-invasive, the equipment is easy to handle and results are delivered quickly. The normal and detailed thermogram of the distal limb was described in horses and the technique allows to evaluate, in equine athletes, the musculoskeletal injuries originated from the routine of intense exercises. In addition, it is an extremely useful diagnostic imaging tool for the early diagnosis of acute and subclinical lesions. The thermography is influenced by environmental factors such as ambient temperature, humidity, solar radiation and convective air movement. It is necessary to be aware of these factors to avoid false-positive or negative results.
