    INPUT: Heart size is exaggerated by low lung volumes and AP technique . There is no focal consolidation or pneumothorax . No pulmonary vascular engorgement or edema . Trace bilateral pleural effusions . Small left retrocardiac opacity is most consistent with atelectasis . Mediastinal and hilar contours are normal . Moderate calcification of the aortic knob . Multiple dilated loops of bowel suggest ileus , though the bowel is incompletely evaluated on this study .
    OUTPUT:
    
1 . Trace bilateral pleural effusions , new since 3 days ago . 2 . Mild left basilar atelectasis . 3 . Multiple dilated loops of bowel in a surgical patient suggest ileus . If clinical concern persists , recommend abdominal radiograph for a more complete evaluation of the bowel .
