Evaluation of radiology as a tool to diagnose pulmonic lesions in calves, for example prior to experimental infection studies.

The aim of the study was to evaluate radiology as a technique to visualize pulmonary lesions in young calves, e.g. as a selection criterion for research animals in order to eliminate animals with lung lesions prior to experimental studies of pneumonia. Five calves with acute clinical signs of pneumonia were included in a direct comparative study of radiological and post mortem findings. Also, a number of animals with no signs of pneumonia were included as controls. The study revealed good agreement between the radiological and post mortem findings. Thus, in conclusion, radiology should be considered as a useful objective tool to predict the presence of pulmonary lesions in young calves.
