Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Compared to ___ at 20 :59 , the overall appearance is similar . Again seen is a rind of pleural fluid and / or thickening about the left lung , with collapse and / or consolidation at the left lung base . Possibility of slight interval increase in the degree of left - sided pleural fluid can not be entirely excluded . The degree of opacity within the aerated portion of left lung appears slightly increased . The appearance of the right lung , with diffuse vascular plethora and prominent right hilum , is probably similar , allowing for technical differences . ET tube tip lies approximately 7 .2 cm above the carina . NG tube tip overlies the gastric fundus . A left subclavian central line tip overlies the proximal SVC . A right IJ central right IJ Swan - Ganz catheter is similar in configuration , with tip suspected to be in the region of the right ventricular outflow tract . No pneumothorax is detected .
    OUTPUT:
    
No definite change compared with ___ . The possibility of slight increase in the left pleural effusion as well as increased opacities in the left mid zone can not be excluded . Appearances in the right and left lung are most suggestive of CHF with interstitial and alveolar edema . The possibility of an underlying infectious infiltrate would be difficult to exclude .
