[Radiation diagnosis of interstitial lung diseases].

The authors analyzed the results of complex radiation study of 1192 patients with various interstitial lung diseases (ILD). An algorithm of differential diagnosis of diffuse and disseminated lesions of the lung was derived by using the findings. The X-ray morphological principle underlies the algorithm. The level of structural lesions of the lung and tissue reactions and the presence of granuloma shadows are the governing criteria for evaluating the gross structure in the differential diagnostic complex. Great emphasis is laid on the significance of computed tomography (CT), high performance CT in particular, which is becoming the priority radiation diagnostic technique in pulmonology. Morphofunctional studies, 99mTc AMA and 67Ga citrate pulmonary scintigraphy in particular, specify the magnitude of changes in the microcirculatory bed and the activity of intrathoracic lymph nodes.

[Radiation diagnosis of Langerhans cell histiocytosis (LCH) of lung].

The authors studied the pattern of X-ray changes detectable in the lungs of 41 patients with LCH. The results of classical X-ray study were supplemented by the data of computed tomography, ultrasonography, and 99mTc and 67Ga citrate radioisotopic studies. The diagnostic values of these techniques were compared. X-ray syndromes of changes in the lung in LCH were found to be interstitial, interstitial and granulomatous, tumorous (focal). The authors emphasize the multisystematic character of a lesion, the phasic nature and progression of the disease into fibrosis.

[X-ray criteria for assessing the activity of lung sarcoidosis at follow-up].

The results of comprehensive X-ray findings in 300 patients with different clinical and X-ray forms of respiratory sarcoidosis who had been registered to be followed up at the Consulting Outpatient Department, Central Research Institute of Tuberculosis Russian Academy of Medical Sciences, were analyzed. The follow-up lasted 3 to 20 years. X-ray study heads the list of the most informative techniques for assessing the activity of sarcoidosis. The time of following up patients with sarcoidosis in dispensary registration groups is recommended in accordance with the recommendations of the sarcoidosis Consensus Commission. X-ray criteria for stabilization of the disease and the optimum methodological complex of radiation diagnosis are defined.

[The x-ray morphological characteristics of the early manifestations of sarcoidosis].

The paper is devoted to an analysis of combined x-ray findings supplemented by CT findings in patients with sarcoidosis detected for the first time with early signs of this disease. A conclusion has been made that apart from lymph node enlargement, sarcoidosis is characterized by lung parenchymal changes which manifest themselves as symptoms of broncho-alveolitis. Characteristic x-ray symptom complexes are described. Roentgeno-semiotics of these changes were compared with the results of morphological investigation of transbronchial puncture specimens. Roentgenologically detectable changes showed good correlation with morphology findings. The authors have also emphasized the importance of morphological verification of this disease at early stages.

[A comparative evaluation of the results of classical x-ray study and computed tomography in patients with exogenous allergic alveolitis].

A correlative study of the results of x-ray investigation using routine methods and computerized tomography (CT) was conducted to specify the roentgenomorphological substrate of changes in patients with exogenous allergic alveolitis. The established complex of routine methods is informative enough to interpret the revealed changes. However, at early stages CT helps to specify semiotics and permits obtaining additional information, particularly on quantitative, i.e. densitometric changes. In diffuse and disseminated pulmonary lesions CT can be used as an additional method.
