摘要：Conventional roentgenograms constitute the groundwork for the evaluation of diffuse interstitial lung disease (DILD). ILO classification with its symbols (additionally extended to granulomatoses) does not comprise pathoanatomic assumptions and does not enter lesion genesis for it could lead to diagnostic misconception. »High resolution« computer tomography (HRCT) provides the evaluation of lesion morphology and disease activity. After having treated our 129 patients with diffuse interstitial lung disease we have come to the conclusion that, beside pneumoconiosis, the application of extended standard ILO symbols are suitable to other interstitial pathology for the homogeneity of morphologic characteristics. As for diagnoses making, in distinction to other methods, it can be said that analyzing roentgenograms of the extended ILO provides high level of lesion evaluation standardization for diffuse interstitial disease as well as substantial congruity with CT finding. It is clear that such analysis cannot be applied in our daily work, however we have both concluded and proved that on conventional roentgenograms the condition of interstitial lesion can roughly be assessed. This is of high importance considering minimal dose of radiation exposure by standard tests in comparison with other radiological techniques. Nevertheless, CT scanning should be performed if there should be the need for the assessment of the morphology and the activity of lesion, to the benefit of our patients.
