Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: ET tube present , tip 3 .4 cm above the carina . Right IJ central line tip is at SVC / RA junction , unchanged . Enteric tube tip extends beneath diaphragm , off film . No pneumothorax is detected allowing for overlying iatrogenic devices . Allowing for differences in positioning , the cardiomediastinal silhouette is probably unchanged . Diffuse vascular plethora , probably with some associated interstitial and alveolar opacities , again seen . The appearance is slightly improved at the lung bases , compared to 1 day earlier . Minimal blunting the right costophrenic angle , but no gross effusion .
    OUTPUT:
    
Extensive vascular plethora and vascular blurring , with more focal opacities at the bases , suggestive of pulmonary edema . Opacities at both bases remain present , but appear slightly improved . The differential includes other etiologies , including infectious and inflammatory infiltrates .
