Labels of 26 segmental airways and 5 subgroups of lobes. BronInt, bronchus intermedius; LMB, left main bronchus; RMB, right main bronchus; sLLL, subgrouped left lower lobe including branches of LB6 and LB8 to LB10; sLUL, subgrouped left upper lobe including branches of LB1 to LB5; sRLL, subgrouped right lower lobe including branches of RB6 to RB10; sRML, subgrouped right middle lobe including branches of RB4 and RB5; sRUL, subgrouped right upper lobe including branches of RB1 to RB3; TriLUL, trifurcation of left upper lobe; TriRUL, trifurcation of right upper lobe
