Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Frontal and lateral views of the chest were obtained . Low lung volumes results in bronchovascular crowding . Mild opacity at the lung bases likely represents atelectasis , but early or developing pneumonia can not be excluded in the appropriate clinical setting . There is no pneumothorax . A small left effusion can not be excluded . Pulmonary edema has improved with mild residual pulmonary vascular congestion . Cardiac and mediastinal silhouette hilar contours are normal allowing for low lung volumes . A nonspecific 1 .3 cm nodule is seen at the right apex and could be related to infection or prior edema . The prior CTA does not include the lung apices to evaluate this .
    OUTPUT:
    
1 . Improved pulmonary edema with mild pulmonary vascular congestion . 2 . Bibasilar opacities may be atelectasis , but pneumonia can not be excluded in the appropriate clinical setting . 3 . 1 .3 cm nonspecific right apical nodule . Recommend repeat radiograph after treatment , preferrably with better lung volumes . Preliminary findings of " no edema , right basilar opacity " were discussed with Dr . ___ in person at 2 : 55 pm on ___ . Updated findings after attending review were emailed to the ED QA nurses at 5 pm on ___ .
