CT image analysis. Left panel. Coronal representation of lungs. Twenty CT images were selected along the cranial-caudal axis. Central panel. Upper part: representative image of an original CT image from a patients included in the study. Lower part: region of interest (ROI) applied to CT image. Right panel: representative image of three ROIs (areas concentric to the visceral pleura: between 0 and 1 cm in blue; 1 and 2 cm in green; and 2 and 3 cm in orange) and quadrants: internal dependent, external dependent, internal non-dependent + external non-dependent). The identification of quadrants was based on the detection of the centroid (or geometrical center) univocally characterizing each lung for each analyzed CT image
