    INPUT: Atelectasis is present at the left lung base , but there is no focal consolidation . Mild to moderate cardiomegaly and mild vascular congestion are noted . Tortuosity of the thoracic aorta is unchanged . There is no pleural effusion or pneumothorax . Osseous structures are grossly intact .
    OUTPUT:
    
1 . Mild to moderate cardiomegaly and mild pulmonary vascular congestion . 2 . Although no acute fracture or other chest wall lesion is seen , conventional chest radiographs are not sufficient for detection or characterization of such abnormalities . If the demonstration of a fracture or other trauma is clinically warranted , the location where there are focal findings should be clearly marked and imaged with either bone detail views or CT scanning .
