Pulmonary blood vessels account for the majority of radiographically visible structures in normal lung. The vascular pattern of pulmonary disease is characterized by changes in vessel size, shape, contour. Changes in size can be classified as hypo vasularity (decreased size) or hyper vascularity (increased size). The pulmonary arteries and veins may be affected separately or simultaneously. In normal lung, the bronchial structures peripheral to the hilar area are not seen clearly. The bronchial pattern of pulmonary disease is characterized by alteractions in bronchial wall thickness and dinsity, or in bronchial lumen diameter. Mixtures of the four lung patterns, i.e. , alveolar, interstitial, bronchial, and vascular, occur frequently. The lung radiographic pattern in an individual animal depends not only on the disease process present, but also on the stage of the disease during which they are radiographed.
