【 摘 要 】

a collapsibility of over 50% was found in the dorsal (n=7) and ventral (n=4) segmental bronchi of the left cranial lobar bronchus, and the left caudal (n=5) and right middle (n=2) lobar bronchus. The collapsibility of the dorsal segment of the left cranial lobar bronchus and left caudal lobar bronchus was statistically different from the ones in the right cranial, caudal, and accessory lobar bronchi (P < 0.05). In conclusion, CT during forced inspiration and expiration can be used as a valuable modality to noninvasively assess bronchial collapse. Furthermore, because more than a 50% collapsibility was found in normal bronchi, a higher diagnostic level is recommended for detecting pathologic bronchial collapse and different criteria of bronchial collapsibility will be needed depending on the location of each bronchus.
