Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The cardiac silhouette is moderately enlarged . The aorta appears unfolded , likely accounting for prominence of the mediastinum . The lung bases , particularly the left , are underpenetrated due to overlying soft tissue . Given this , no definite focal consolidation is seen . There is no pleural effusion or pneumothorax . No overt pulmonary edema is seen .
    OUTPUT:
    
Moderately enlarged cardiac silhouette . Prominence of the mediastinum is most likely due to an unfolded aorta , however , if there is concern for acute mediastinal process , chest CTA is more sensitive . No focal consolidation to suggest pneumonia .
