[Significance and role of radiation studies in complex diagnosis of exogenous allergic alveolitis].

The authors highlight X-ray symptom complexes (XRSC) (emphysematointerstitial, parenchymatointerstitial, and pneumonic) which are characteristic of exogenous allergic alveolitis (EAA). The above XRSC are comparable with the clinical types of EAA. The semeiotics typical of each XRSC and the value of radiation diagnostic methods in specifying changes in lung tissue and intrathoracic lymph nodes, the activity of the process are presented. Each study (classical X-ray, CT, radionuclide scintigraphy) has its own advantages and resolution limits. Radiation studies in the diagnosis of EAA should be used purposefully in combination with other studies (immunology, external respiratory function test, bacterial cytology, morphology) by taking into account the clinical manifestations of the disease.
