Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Compared with the prior film , an NG tube has been placed . The tip is poorly delineated . I suspect that it overlies the gastric fundus . If the sideport is present is not well seen and can not be localized . A left - sided pacemaker type device is again noted , similar in configuration . Is still difficult to trace the thinnest lead is better seen , but still difficult 2 trace in its entire T , this may very well be due to technical factors . Cardiomediastinal silhouette is enlarged , with prominence of either the right heart border right pulmonary artery , similar to prior . There is upper zone redistribution and diffuse vascular plethora , compatible with CHF , progressed compared with the prior study . Minimal blunting of the right costophrenic angle again noted . Equivocal blunting of left costophrenic angle . Bibasilar atelectasis . Again seen is increased retrocardiac density , consistent with left lower lobe collapse and / or consolidation . No pneumothorax detected . Incidental note is made a linear of increased density in the upper thoracic vertebral body , question L1 , with diminished height of the vertebral body . Taken together , the appearance is suggestive of kyphoplasty or vertebroplasty .
    OUTPUT:
    
NG tube tip difficult to trace , likely over fundus . An NG tube sideport , if present , is not distinctly visible on this film . Enlarged cardiomediastinal silhouette with suspected pulmonary artery enlargement , similar to the prior study . Vascular plethora and interstitial edema , consistent with mild CHF , increased compared with the prior study . . Left lower lobe collapse and / or consolidation , similar to prior . Bibasilar atelectasis . Minimal blunting of the right and question left costophrenic angles .
