Radiobiologic and pathologic characteristics of the irradiated lung and roentgenographic aspects.
OBJECTIVE
Experimental radiobiologic factors help to better understand and interpret the development of radiographic alterations in lung tissues due to radiant treatments. In this paper the authors summarize the radiologic factors and technical bases about radiotherapy of the lung.


METHODS
The conventional radiologic iconography has been examined in a large series of patients (n = 2151) with iatrogenic pulmonary lesions determined by various types of antineoplastic radiant treatments at the Istituto Nazionale Tumori of Milan.


RESULTS
A radiologic control and a long follow-up is essential to assess the successive phases of postactinic lesions due to "passive" irradiation therapy for any type of non-endothoracic tumor as well as those due to "necessary" lung radiotherapy for endothoracic neoplasms.


CONCLUSIONS
A strict relation has been found between the aspects in conventional radiologic iconography and the corresponding lesions in the irradiated lung.
