Importance of ground-glass attenuation in chronic diffuse infiltrative lung disease: pathologic-CT correlation.
Abstract
PURPOSE: To correlate areas of ground-glass attenuation at computed tomography (CT) with findings at open lung biopsy in chronic diffuse lung disease. MATERIALS AND METHODS: The cases of 26 patients were included on the basis of (a) extensive areas of ground-glass attenuation as the predominant (n = 17) or exclusive (n = 9) abnormality at CT in the absence of honeycombing and (b) histologic evaluation at open lung biopsy. Severity of ground-glass attenuation was scored in the lobe sampled at biopsy, with separate analysis of associated lung changes. RESULTS: Correlation of CT with histologic findings at the 37 biopsy sites demonstrated that ground-glass attenuation corresponded to inflammation in 24 (65%) cases and to fibrosis in 13 (54%) cases. Eleven of the 13 patients (85%) with fibrosis had traction bronchiectasis or bronchiolectasis. These findings were not present in any of the patients with inflammation. CONCLUSION: In patients with chronic diffuse infiltrative lung disease, areas of ground-glass attenuation not associated with traction bronchiectasis or bronchiolectasis are a reliable indicator of inflammation.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
