    INPUT: Portable supine radiograph shows interval placement of a left - sided subclavian line , the tip of which terminates in the upper to mid SVC . An endotracheal tube terminates approximately 5 cm above the carina . A transesophageal tube is seen , the tip is not visualized . Supine technique exaggerates central pulmonary vasculature engorgement . Again seen is a right basilar opacity , not significantly changed since the prior examination , which may represent aspiration or edema in the appropriate clinical context . No definite pleural effusion or pneumothorax is identified , though sensitivity is limited on supine film .
    OUTPUT:
    
New left subclavian line terminating in the proximal to mid SVC . Otherwise largely unchanged examination with right basilar opacity which , in the appropriate clinical context , may represent aspiration / a component of edema .
