Objectives
Interlobar collateral ventilation was discovered by Van Allen et al. [1] about 100 years ago and has been proven since then. Recently, some papers have been published that use the latest equipment and noble gases [2-6], but these equipments cannot distinguish IIF (Incomplete Interlobar Fissure) and CIF (Complete Interloper Fissure). Here, we report on our analysis of pulmonary lobar collateral ventilation from the inspiration and expiration CT using conventional CT scanners.
