An analysis of variations in the bronchovascular pattern of the right upper lobe using three-dimensional CT angiography and bronchography

Abstract

We explored the bronchovascular pattern and the frequency of variations in the right upper lobe using a large number of 3DCT images. The incidences of variations differed, sometimes significantly, from those noted by previous reports. Moreover, we report some new branching variations. Our data can be used by thoracic surgeons to perform safe and precise lung resections.
