[Idiopathic interstitial pneumonia; evaluation by high-resolution CT and pathologic correlation].
In order to identify and classify the basic CT appearances of interstitial pneumonia, radiologic -pathologic correlative study was performed using inflated and fixed lungs from autopsy and surgery. The patterns of the abnormalities on the CT images of interstitial pneumonia were classified into 7 categories. Important pathological changes which affected the CT images were alveolar collapse and airway dilatation. Based on the result of above study, we analyzed CT of 22 patients with IIP. The lesions which were classified into a hazy density, micronodular densities, confluence of various sized ring like shadows and subpleural bullous changes were frequently recognized together mostly in the periphery of the lung.
