[Thin-section computed tomography of the bronchi: right middle lobe, left lingular division, and lower lobes]

Thin (2 mm) section contiguous computed tomographic (CT) scans were obtained through the bronchi of the right middle lobe, the left lingular division, and the lower lobes in 24 patients. All segmental bronchi were identified except subsuperior and medial basilar segmental bronchi. Subsegmental bronchi of the left inferior lingula were seen in only 17%, but other subsegmental bronchi in greater than 75%. Variations in branching patterns were discussed.
