Impalpable Pulmonary Nodules With Ground-Glass Opacity.

The article focuses on the study which aims to test the credibility of high-resolution CT scanning in detecting small bronchioloalveolar carcinoma or atypical adenomatous hyperplasia that appears as a ground-glass opacity (GGO). To test, impalpable GGO lesions are marked and resected under C-arm fluoroscopy. The results reveal that the use of fluoroscopy to cut sections from resected specimens after preoperative marking with lipiodol was useful for making pathologic sections of impalpable GGOs.
