Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Low lung volumes accentuates the size of the cardiomediastinal silhouette . The heart size appears at least mildly enlarged . There is crowding of the bronchovascular structures but no overt pulmonary edema is demonstrated . Assessment of the lung bases , particularly the left lung base , is limited due to the presence of low lung volumes and exclusion of the left costophrenic angle . Patchy bibasilar opacities likely reflect atelectasis . No right - sided pleural effusion is visualized . There is no pneumothorax .
    OUTPUT:
    
Limited study due to low lung volumes . Patchy opacities in the lung bases likely reflect atelectasis , though the left lung base is not completely imaged . Consider repeat PA and lateral views with improved inspiratory effort when the patient is able to better assess the lung bases .
