Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: An ET tube is present , tip lies approximately 3 .8 cm above the carina . An NG tube is present , the tip extends beneath the diaphragm , off the film .A Swan - Ganz catheter is present , tip overlies the main pulmonary outflow tract . No pneumothorax is detected . The cardiomediastinal silhouette is unchanged . Patchy increased retrocardiac opacity is similar , but probably slightly worse . There is blunting the left costophrenic angle which could reflect presence of a small left effusion . There is hazy opacity at the right lung base , most likely representing atelectasis . The right costophrenic angle is excluded from the film , limiting the assessment for small pleural effusion . Doubt CHF .
    OUTPUT:
    
ET tube tip approximately 3 .8 cm above the carina . Additional lines and tubes as described . Patchy opacity in retrocardiac region consistent with left lower lobe collapse and / or consolidation is probably slightly worse . A small left effusion is also present .
