[Roentgenographic pattern of interstitial pneumonia and allergic alveolitis (author's transl)]

Roentgenographic examination of the lungs permits diagnosis of inflammatory and allergic pulmonary disease with predominantly interstitial and less alveolar involvement in which pulmonary fibrosis may develop. Reaction of the sensitised lung to allergic exposure causes typical roentgenological patterns. Development of pulmonary fibrosis in interstitial lung disease can be prevented be early cortison therapy.
