Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: An NG tube is present , the tip extends beneath the diaphragm and overlies the upper stomach . The sideport overlies the gastric fundus , likely immediately distal to the GE junction . The ET tube has been removed . Left IJ central line tip overlies the cavoatrial junction , similar to prior . The cardiomediastinal silhouette is unchanged . Mild crowding of vessels about the left - greater - than - right superior hila is again noted . Probable subsegmental atelectasis at the right base medially . Retrocardiac could at retrocardiac density this appears slightly improved compared with the prior film . No gross effusion . No pneumothorax detected . . Incidental note made of bilateral cervical ribs .
    OUTPUT:
    
NG tube tip overlies the stomach . Sideport probably lies immediately distal to the GE junction . Clinical correlation regarding possible advancement is requested . Interval improvement in retrocardiac density , though retrocardiac density persists . Mild crowding of bronchovascular markings about the hila , similar to prior . Probable atelectasis at the right base medially . Incidental note made of prominent bilateral C7 cervical ribs .
