Abstract

This study describes ultrasonography of the lungs and pleura in healthy camels (Camelus dromedarius). The different layers of the thoracic wall appeared as narrow bands of variable echogenicity. Reverberation artefacts appeared as lines of variable echogenicity that ran parallel to the pulmonary surface medial to the pleura. Because of its air content, the pulmonary parenchyma was not visualised in all camels. On the right side, the pulmonary surface was seen in the 5th through the 10th intercostal space (ICS). In addition, it was imaged in the 11th ICS in 20 camels and in the 4th ICS in three camels. The dimension of the ventral lung border was largest at the 4th ICS and smallest at the 11th ICS. The echogenic line on the surface of the lung, consisting of the costal and the parietal pleurae, was 1 to 4 mm thick. The left pulmonary surface and pleura were imaged with approximately the same frequencies as the right side. At this side, only the pulmonary surface and pleura were imaged in 15 camels in the 11th ICS. In conclusion, ultrasonography of the lungs and pleura provides information that can be used as a reference when examining camels suspected to have respiratory diseases.
