Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Single AP intraoperative view of the chest provided . An ETT is noted terminating 2 .7 cm above the carina . Lung volumes are low with worsened bibasilar atelectasis . A curvilinear opacity overlying the proximal trachea at the cervicothoracic junction , may represent a malpositioned orogastric tube given the history of orogastric tube placement and lack of visualization of the tube below this level . Of note , the subsequent chest radiograph shows an appropriately positioned OG tube . There is no effusion , or pneumothorax . Imaged osseous structures are intact . No free air below the right hemidiaphragm is seen .
    OUTPUT:
