Diagnostic ultrasonography in cattle with thoracic disease

The pleura and lungs were evaluated by means of sonography in 55 bovine patients with diseases of the thoracic cavity. For these ultrasound examinations, a range of transducers was used. As the lung surface was most often involved in cases of pulmonary disease, it was possible to detect ultrasonographically bronchopneumonia, consolidation, pleural effusion, pulmonary emphysema and pleuritis. Determination of the amount of lung tissue affected provided prognostic information. It was not possible to visualise lesions located deeper within the lungs where peripheral tissue was not affected. A diagnosis of thoracic disease was made on the basis of clinical and ultrasonographic findings and confirmed in 33 cases at necropsy. (C) 2003 Elsevier Ltd. All rights reserved.
