Adjacent lobe volume expansion vs. treated lobe volume reduction (as % of total lung volume). The significant correlation suggests compensatory expansion of the adjacent lobes after SABR, representing the desired effect of SAVR for emphysema. The linear correlation includes adjacent lobes receiving V60BED3 ≤0.5 % TLV (n = 48, black dots) and excludes adjacent lobes receiving V60BED3 ≥0.5 % TLV (squares), correcting for the treated volume extending across the lung fissure and encompassing adjacent lobe volume
