Two patients with GGNs. a–e A female with a GGN in the left lower lobe. The GGN was incidentally discovered on June 21, 2019. At the follow-up, the VDT was fewer than 400 days and was classified into the fast-growth group. f–j A male with a GGN in the right lower lobe. The GGN was incidentally discovered on February 11, 2015. At the follow-up, the VDT was more than 400 days and was classified into the slow-growth group. GGNs: ground glass nodules, VDT = volume doubling time
