From: Three-dimensional substructure measurements for the differential diagnosis of ground glass nodules
Correlation between the total volumes (TVs) of ground-glass nodules (GGNs) in the PIA group and the difference between the maximum and the peak CT numbers (M-P) of nodules using Spearman correlation analysis. Along with TV increasing, M-P values also increased, reflecting that the heterogeneity of the nodules, between the solid core and the principal, increased as well
