Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There are low lung volumes and the patient appears somewhat kyphotic in position . Low lung volumes cause vascular crowding although there may be a mild component of vascular congestion . Perihilar opacities most likely relate to vascular congestion although underlying infectious process or aspiration at the left lung base or right perihilar region is not entirely excluded . No large pleural effusion is seen . There is no evidence of pneumothorax . Cardiac and mediastinal silhouettes are grossly stable given differences in technique and patient position .
    OUTPUT:
    
Low lung volumes and patient in a somewhat kyphotic position the examination is slightly suboptimal . Low lung volumes cause vascular crowding although there may be mild pulmonary vascular congestion . Right suprahilar and left infrahilar opacities may relate to pulmonary vascular congestion although infectious process or aspiration not entirely excluded in the appropriate clinical setting .
