Abstract

Computed Tomograms of 45 patients with or without lung mass were reviewed to determine the characteristics of the major and minor fissures. Also pulmonary vascular distibutions were analyzed to localize each pulmonary lobe. The results were as follows; 1. Each major fissure area was imaged frequently as lucent band, less frequently dense band. 2. The minor fissure areas were imaged as oval or triangular lucent zones. The oval or triangularlucent zones were as same frequency. 3. Avascular planes without above mentioned lucent zones were also correspond to minor fissure areas. 4. Slices of avascular zones were observated between pulmonary arteries to posterior segment or apicoposterior segment of upper lobe and to superior segement of lower lobe on both lungs.
