Distribution densities (diagonal) and bivariate scatterplots (off-diagonal) among statistically significant morphological variables for benign and malignant lesions. Variables include number of vessel segments (NV), number of branch points (NB), mean tortuosity (τ_mean ), maximum tortuosity (τ_max ), fractal dimension (FD), and mean of bifurcation angle (BA_mean ). For each distribution graph (diagonal figures), the orange line corresponds to the malignant lesions and the blue to the benign ones. In the off-diagonal scatterplots, the red dots correspond to the malignant lesions and the cyan to the benign ones.
