Use of a Radiomics Model to Predict Tumor Invasiveness of Pulmonary Adenocarcinomas Appearing as Pulmonary Ground-Glass Nodules

Figure 1

CT images show preinvasive lesions and invasive adenocarcinomas. (a) A 7 mm mGGN (arrow) is shown in the anterior segment of the right upper lobe in a 53-year-old woman. This nodule was confirmed pathologically as a preinvasive lesion (AAH). (b) A 13 mm mGGN (arrow) is shown in the anterior segment of the right upper lobe in a 53-year-old woman. This nodule was confirmed pathologically as a preinvasive lesion (AIS). (c) An 11 mm mGGN (arrow) is shown in the posterior segment of the right upper lobe in a 35-year-old woman. This nodule was confirmed pathologically as an invasive pulmonary adenocarcinoma (MIA). (d) A 21 mm mGGN (arrow) is shown in the posterior segment of the right upper lobe in a 35-year-old woman. This nodule was confirmed pathologically as an invasive pulmonary adenocarcinoma (IAC). Note: AAH=atypical adenomatous hyperplasia; AIS=adenocarcinoma in situ; MIA=minimally invasive adenocarcinoma; IAC=invasive adenocarcinoma.
