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.
