Ultrasonographic findings in adult cattle with chronic suppurative pneumonia

Chronic suppurative pneumonia is a common condition affecting cattle. Accurate diagnosis and delineation of pathology prove difficult when based on lung auscultation. Ultrasonography has been used in bovine fertility management for over 25 years, but it is less commonly used to examine the lungs and pleurae of cattle with suspected respiratory disease. This article presents a series of sonograms obtained from the same animals using both 5MHz linear and 5MHz sector scanners, and correlates the findings with postmortem examination material wherever possible.
