This study compared the radiographic and B-mode and Doppler ultrasonographic findings of the thorax, excluding the heart, of dogs (27) and cats (2) whose thoracic radiographys revealed an potential acoustic window. The aim of this study was to identify advantages and limitations of each technique, besides to determine if these additional informations had impact on differential diagnoses and outcomes. The B-mode ultrasonographic examination showed the following advantages: better estimative of the amount of pleural effusion, qualitative informations regarding its nature, identification of submerged structures, differentiation between solid and cystic nodules, as well as definition of its location in the lung parenchyma or other thoracic compartments. The Power Doppler ultrasonography allowed to assess the blood pattern supply of nodules and masses, and differentiate between vessels and fluid bronchograms. Ultrasonographic limitations were based in the impossibility of evaluation of the lung parenchyma in the absence of an acoustic window and requirement to be guided by previous radiographic examination. The radiographic advantages were the possibility of location of pulmonary lesions in any depth in the absence of pleural effusion and mainly because provided a panoramic view of the thoracic cavity involvement. Informations obtained by the ultrasonographic examination provided impact on the differential diagnosis in 62.06% of the cases. In 27.5% of the cases, additional informations also influenced the outcome.
