Computed tomography appearances of bronchogenic carcinoma associated with bullous lung disease.

abstract：OBJECTIVE:Prior work has described the relationship between pulmonary vascular pruning on computed tomography (CT) scans and metrics of right-sided heart dysfunction in smokers. In this analysis, we sought to look at pruning on a lobar level, as well as examine the effect of the arterial and venous circulation on this ...
