Abstract

PURPOSE
This study was performed to evaluate the features of pulmonary lobes and fissure in Korean and to compare with the previous results.
MATERIALS AND METHODS
HRCT scans of 82 healthy Korean adults, performed with scan interval of 1.5/2.0 cm, were reviewed.
RESULTS
Located mostly on inner aspect, incidences of incomplete oblique and horizontal fissure were 60% (Rt 48%, Lt 39%) and 51% respectively, lower than 70--80% and 60--75% of western studies. Superolateral oblique fissure, inferior accessory fissure, left horizontal fissure and other accessory fissure were shown in 1%, 13%, 7%, and 8% respectively. Lower lobe upper part faced laterally (Rt 91%, Lt 82%) while lower part faced medially (Rt 61%, Lt 79%). Right middle lobe ws highest posteromedially (49%) and was convex (97%).
CONCLUSION
Features of pulmonary lobes and fissure in Korean were similar to the results of previous reports but with lower incidence of variation.
