    INPUT: An NG tube is present , tip overlies the gastric fundus / proximal stomach . The sideport lies in the region of the GE junction , not definitely beyond it . Again seen is a a left - sided dual lead pacemaker with lead tips over the right atrium right ventricle . Thin wirelike density in may represent an epidural catheter . There is linear somewhat patchy opacity at the left lung base , new compared with ___ . No CHF . Long was are otherwise grossly clear , without CHF , other opacities , or gross effusion . Minimal blunting of both costophrenic angles is present . Heart size is at the upper limits of normal . The aorta is mildly unfolded . There is curvilinear lucency below the right hemidiaphragm
    OUTPUT:
    
1 . NG tube tip over gastric fundus / proximal stomach . The side port lies in the region of the GE junction , but does not definitely extend beyond the GE junction . 2 . Patchy opacity at left lung base , new compared with ___ chest x-ray hand apparently new compared with abdominal CT from ___ . Question atelectasis . In appropriate clinical setting , the differential diagnosis could include an pneumonic infiltrate or changes due to aspiration . 3 . Unusual curvilinear lucency immediately below the right hemidiaphragm . The appearance is not typical for intraperitoneal air . Question unusual artifact due to overlying bowel or superimposed diaphragmatic shadows . However , the possibility of free intra-abdominal air can not be entirely excluded . If clinically indicated , a lateral view could help for further assessment .
