[Radiogenic pneumopathy--synopsis of roentgen image and electron microscopy findings]

Radiation-induced pneumapathia is one of the most frequent complications after radiotherapy to the chest and occurs especially after radiation of bronchial carcinoma (frequency 40-70%, using 50 Gy). The broad ranges of reported frequency indicate differences in defining the degree of radiation-induced damage (clinical picture, plain film, and lung function parameters). This study is to compare plain film findings with electromicroscopy in order to correlate radiological signs with the underlying histo-morphological process.
