What can cause interstitial pattern in the lungs?
fibrosis, lymphoma, resolving alveolar disease
What are the more common reasons for unstructured interstitial pattern?
obesity, poor inspiration, older dog, edge enhancement on digital radiographs
What does HELP ME stand for in alveolar lung pattern causes?
hemorrhage, edema, lymphoma, pus, mediastinal shift
What does a cranioventral alveolar pattern suggest?
pneumonia

cardiogenic edema in dogs
What does a caudo dorsal alveolar pattern suggest?
non cardiogenic edema (obstruction, elctrocution, near drwoning, sepsis, seizures, head trauma)
viral pneumonia
What does a patchy alveolar pattern suggest?
hemorrhage, fungal pneumonia, heart failure in cats**, some neoplasms
What does a diffuse alveolar pattern suggest?
fungal pneumonia, chronic HF, lymphoma, sepsis (ARDS)
What does bronchiectasis look like on radiography?
