ABSTRACT: This study compared radiographic and B-mode and Doppler ultrasound exams of the thoracic cavity, excluding the heart, in canine and feline species, in which the radiographs revealed the formation of a potential acoustic window. The objectives were to demonstrate the advantages and limitations of each technique and to determine whether the additional information influenced the differential diagnosis as well as the outcome of each case. The advantages of B-mode ultrasonography included: better qualitative and quantitative evaluation of pleural effusions, an improved ability to determine whether a nodule was solid or cystic and easier determination of the location in the pulmonary parenchyma. The Power Doppler ultrasound evaluated the blood supply pattern of the nodules and masses and differentiated between vessels and fluid bronchogram. A limitation of the ultrasound examination was the need to be guided by the previous radiography. The advantages of the radiographic examination included the possibility of localizing pulmonary lesions at any depth in the absence of a pleural effusion and providing a panoramic view of the extent of the thoracic disease. The ultrasound examination influenced the differential diagnosis in 18 (62.06%) cases and influenced the outcome of 8 (27.58%) cases.
