From: Three-dimensional substructure measurements for the differential diagnosis of ground glass nodules
Boxplots comparing the differences between maximum and peak CT numbers (M-P) of ground-glass nodules (GGN) for distinguishing between pre-invasive adenocarcinoma (PIA) and invasive adenocarcinoma (IAC), between solitary GGNs and multiple GGNs, and between pure GGNs and mix GGNs. IACs, isolated nodules and mix GGNs had a significantly higher M-P values than PIAs, multiple nodules and pure GGNs respectively
