Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Rotated positioning . ET tube tip approximately 5 .7 cm above the carina at the level of the lower clavicular heads . NG tube extends beneath the diaphragm , off the film . A right subclavian PICC line tip most likely overlies proximal SVC , allowing for rotation . Additional tubing with pigtail tip over the lower left chest or upper left abdomen is again noted . Again seen is marked cardiomegaly . On today 's exam , the focal opacities in the left lung apex appear slightly improved . Left lower lobe collapse and / or consolidation with air bronchograms remains present , similar to the prior film . Vascular plethora in the right lung is consistent with ongoing CHF . Probable small right of fusion , with right base atelectasis , similar to the prior film .
    OUTPUT:
    
1 . Partial interval improvement of opacity in the left lung apex compared with the most recent prior film . Compared with ___ at 08 :35 a .m . , aeration at the left lung apex has clearly improved . 2 . Continuing left lower lobe collapse and / or consolidation . Mediastinal shift difficult in light of the patient rotation , but may very well be similar to the prior film . 3 . CHF , with suspected small right effusion as well is right base atelectasis .
