The feasibility of non-contrast enhanced plus contrast-enhanced computed tomography in discriminating invasive pure ground-glass opacity from pre-invasive pure ground-glass opacity

摘要

volume-rendering technique CT image and Pathological sections (hematoxylin-eosin staining,original magnification× 40) (a, b) CT image of pure ground-glass nodules opacity in the right medium lobe of a 67-year-female. Image show that vessels passed through the GGO were eliminated manually. Pathological results confirmed the diagnosis of adenocarcinoma in situ (AIS). c, d CT image of pure ground-glass nodules opacity in the right medium lobe of a 52-year-female. Pathological results confirmed the diagnosis of minimally invasive adenocarcinoma (MIA). e, f CT image of pure ground-glass nodules opacity in the left upper lobe of a 63-year-male. Pathological results confirmed the diagnosis of invasive adenocarcinoma (IAC)
