摘要：

The influence of body position on volume and X-ray attenuation of the lungs of 3 beagles was investigated with computed tomography. In left and right lateral recumbency, the dependent lung had decreased volume and increased X-ray attenuation compared with ventral recumbency. Volume and X-ray attenuation of the nondependent lung were unchanged. In dorsal recumbency, there was a vertical gradient of X-ray attenuation being increased dorsally and decreased ventrally compared with ventral recumbency where regional differences in X-ray attenuation were not found. Results indicate a risk of overlooking a mass in the dependent pulmonary parenchyma of dogs in lateral and dorsal recumbency. Regional differences in X-ray attenuation of the lungs of dogs can be avoided if the radiographs are obtained with the dog in ventral recumbency.
