Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: An ET tube is present , tip approximately 5 .1 cm above the carina . An NG tube is present , tip and side - port extending beneath diaphragm . Tip extends beyond the edge of the film . A right IJ central line is present , tip over distal SVC . No pneumothorax is detected . There are low inspiratory volumes . Cardiomegaly is unchanged . Again seen is dense retrocardiac opacity obscuration left hemidiaphragm , consistent left lower lobe collapse and / or consolidation . Small left effusion is likely present . There is patchy opacity at the right base , similar to the prior film , with trace blunting of the costophrenic angle . There is upper zone redistribution , without overt CHF . No free air detected beneath the diaphragms on this supine film .
    OUTPUT:
    
Lines and tubes as described . Left lower lobe collapse and / or consolidation patchy opacity right lung base and possible small bilateral effusions are similar to the prior study . Upper zone redistribution , without other evidence of CHF , also similar to the prior study .
