Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The ET tube terminates approximately 2 .5 cm above the carina . There is an enteric tube which extends below the diaphragm with the tip in the proximal stomach ; however , with the side port at the gastroesophageal junction , and must be advanced . The heart size is normal . The aorta appears to be tortuous . Apparent shift of the mediastinal structures to the right may be rotational ; however , there is also a component of volume loss in the right lung , with evidence of atelectasis and asymmetric elevation of the right hemidiaphragm . There is an area of increased lucency at the right lung base below the minor fissure , which could be secondary to a large bulla given patient 's history of COPD or a loculated pneumothorax . The left lung appears to be clear . At the upper right lung there is a nodular opacity measuring 1 .1 cm x 1 .1 cm . Linear fibrotic opacities at the medial right lung base is consistent with scarring .
    OUTPUT:
    
1 . ET tube terminates appropriately above the carina of approximately 2 .5 cm . 2 . Nodular opacity in the upper right lung measures 1 .1 cm x 1 .1 cm unclear whether artifactual and possibly external to the patient or a true nodule ; close attention on followup imaging is recommended , given concern for malignancy . 3 . Area of hyperlucency at the right lung base may be secondary to a bulla given patient 's history of COPD or a loculated pneumothorax . This is of indeterminate chronicity given absence of priors . 4 . Enteric tube appears to terminate at the proximal stomach ; however , the side port is in the distal esophagus , and should be advanced so that it is well within the stomach . ___ were d / w Dr . ___ at 6 : ___p on the day of the exam by phone by Dr . ___ ___ .
