Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: An ET tube is present , in satisfactory position approximately 3 .2 cm above the carina . A left IJ central line is present , tip over mid SVC . An NG tube is present , tip extending beneath the diaphragm off the film . No pneumothorax is detected . Compared to the prior film , again seen are focal relatively confluent opacities in the left lung laterally and in the right perihilar region , though no clear cut air bronchograms are identified . There is also upper zone redistribution and diffuse vascular blurring , consistent with CHF . There is increased left lower lobe collapse and / or consolidation , now with obscuration of the left hemidiaphragm and a small left effusion . Probable atelectasis at the right lung base . Minimal opacity in the right costophrenic angle could represent either atelectasis or small amount of fluid . Spinal hardware noted .
    OUTPUT:
    
1 . ET tube , NG tube , and left IJ central line in satisfactory position . No pneumothorax detected . 2 . CHF , which appears more pronounced than on the earlier film 3 . Multifocal opacities could represent either confluent CHF or multifocal pneumonia . Other etiologies are not excluded . In particular , attention to the right hilum after treatment of acute processes is recommended to exclude hilar enlargement . 4 . Considerable worsening of left lower lobe collapse and / or consolidation , now with a small effusion .
