Radiologic Parameters Predicting the Histologic Invasiveness of Pure Ground-glass Nodules

Among pure ground-glass nodules (pGGNs), invasive adenocarcinoma (IAD) was significantly correlated with larger size on computed tomography (CT) and high maximum standardized uptake value (SUVmax).• The cutoff CT size and SUVmax values for predicting histological invasiveness were set at 18 mm and 1.5, respectively.• Overall, 80% of the pGGNs with CT sizes ≥18 mm and SUVmax ≥1.5 were IAD; conversely, 85% of the pGGNs with CT sizes <18 mm and SUVmax <1.5 were non-IAD.
