Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The endotracheal tube is again seen approximately 3 cm above the carina . A left subclavian central venous catheter is unchanged in position and terminates in the mid to low SVC . A nasogastric tube is within the stomach but contains a hairpin turn which may cause kinking . The tip is likely in the antrum . An unidentified additional line with a radiopaque cylinder overlies the neck adjacent to the endotracheal and nasogastric tubes , and was not present on the prior radiograph . It is likely external to the patient . An area of linear atelectasis in the right lower lung is more prominent than on the prior study . The well - expanded lungs are otherwise clear . There is no pneumothorax or pleural effusion . The hilar and cardiomediastinal contours are normal . Pulmonary vascularity is normal . The patient has had a past wedge resection of the right lung .
    OUTPUT:
    
1 . Endotracheal tube 3 cm above the carina . 2 . Lung expansion is adequate . 3 . More prominent right lower lung atelectasis . 4 . A redundant loop of nasogastric tube is possibly kinked within the stomach and should be retracted to straighten it if indicated . 5 . Unidentified new line , likely external to the patient , overlying the neck .
