Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: ET tube tip lies approximately 4 .6 cm above the carina . NG tube tip extends beneath diaphragm , off film . Right IJ central line tip probably overlies the upper right atrium , though the cavoatrial junction is not well delineated . The cardiomediastinal silhouette is grossly unchanged . Again seen are diffuse opacities throughout both lungs . Allowing for technical differences , these are probably similar to the prior study . No gross effusions identified .
    OUTPUT:
    
Lines and tubes as described . Possibility that the tip of the right IJ line overlies the upper right atrium can not excluded . Doubt significant interval change . Diffuse interstitial and alveolar opacities in both lungs . Allowing for technical differences , this is likely similar to the prior study . The appearance is compatible with CHF and pulmonary edema . In the appropriate clinical setting , diffuse bilateral infectious and inflammatory infiltrates could have a similar appearance .
