Abstract:
The present work entitled “Radiographic lung patterns of different respiratory conditions in dogs” was conducted on dogs presented to Veterinary Clinical Complex, Department of Veterinary Surgery and Radiology, College of Veterinary Science, Tirupati. The dogs with respiratory signs clinically observed were subjected for radiographic examination to find out the radiographic lung patterns, also to estimate the haematological and biochemical parameters corresponding to the lung pathology in the clinical conditions. X-ray machine (1000 mA) with computerized radiography system was utilized to perform the radiographic examination. Among the 45 cases under study, alveolar pattern featured by air bronchograms suggesting different stages of pneumonia was noticed in 13 cases. Radiographic interstitial pattern observed in 12 cases which revealed increased radiographic density involving structures of lung parenchyma/interstitium, displacing the normal lung. Vascular pattern was noticed in 8 cases which showed radiographic pattern with increased radiographic density of vessel margin. Bronchial radiographic pattern observed in 7 cases suggested chronic bronchitis and bronchial mineralization featured by tram lines/ donut pattern. Few animals showed mixed radiographic lung patterns involving any combination of interstitial, bronchial, vascular and alveolar patterns. The radiographic lung patterns provided the information about the involvement of lung parenchyma, bronchi or blood vessels in the lungs, which could be correlated with other underlying etiological factor. The results are highly informative before proceeding to administration of anaesthesia, fluids and any surgical interventions.
