Abstract

Eleven bovines under 22 months of age showing symptoms of chronic pneumonia were examined by ultrasound to evaluate diagnostic significance. The ultrasonic images of the lung obtained included reverberation and/or acousitc shadow in the healthy lung, air echo pattern in aerated pneumonia, low-level echo pattern in non-aerated pneumonia, and reverberation and/or acoustic shadow in emphysema. Necropsy showed chronic pneumonia in all cases. It was revealed that the diagnosis of chronic pneumonia could be made by detection of a wide-spread lesion of non-aerated pneumonia by ultrasound, which may suggest both a poor prognosis and poor growth rate.
