Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Assessment is limited by patient rotation . Heart size is at least moderately enlarged . Aorta is tortuous . Mediastinal contour is difficult to assess given the degree of patient rotation . There may be minimal pulmonary vascular congestion . No large pleural effusion or pneumothorax is seen . Linear opacities at the lung bases likely reflect areas of atelectasis . Multilevel degenerative changes are noted in the thoracic spine .
    OUTPUT:
    
Limited study due to rotation . Probable mild pulmonary vascular congestion and bibasilar atelectasis .
