Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A Dobhoff tube is present . On view 1 . , the tip overlies the distal mediastinum , possibly reaching the GE junction . On view 2 . , the tip is not visualized and presumably extends beneath the GE junction . Based on this common additional view to include the abdomen would be required to see the radiopaque tip . Compared with the prior film , cardiomediastinal silhouette is grossly unchanged . However , there is increased vascular engorgement and mild vascular blurring at the bases , consistent with CHF . The possibility of small effusions can not be excluded . PICC line again noted in the mid to distal SVC .
    OUTPUT:
    
1 . On the second film , the radiopaque Dobhoff tip tube extends beyond the GE junction , into the abdomen , but is not included on the film . 2 . Compared with the prior film , there is now evidence of CHF , with vascular engorgement and probable interstitial edema at the bases . Possible small bilateral effusions .
