Particularly, the segment 8 of the right lower lobe was severely emphysematous destructed and hyperinflated in the MDCT scan (Fig. 1).
Three months following valve treatment, the MDCT scan showed a complete collapse of the segment 8.

Thus, the radiological assessment showed the optimal result following segmental treatment, which was associated with a subjective clinical relevant improvement (see Fig. 3).
