Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The endotracheal tube is appropriately positioned , no less than 4 .3 cm above the carina . A nasogastric tube courses through the esophagus and into the expected location of the stomach . The sideport may be near the gastroesophageal junction The there are median sternotomy wires and mediastinal surgical clips . The lung volumes are low . Bilateral perihilar opacities and bronchial cuffing are consistent with pulmonary vascular engorgement . The there is no pneumothorax . The there is a convex , sharply demarcated , rounded opacity in the lower left chest of unclear etiology , possibly an elevated hemidiaphragm . There are likely small bilateral pleural effusions .
    OUTPUT:
    
1 . Appropriately positioned endotracheal tube . The nasogastric tube could be advanced to ensure the sideport is in the stomach . 2 . Central pulmonary vascular engorgement . Likely small bilateral pleural effusions . 3 . Convex opacity in the left lower chest of unclear etiology , possibly elevated hemidiaphragm . This area is incompletely imaged . Consider repeating the radiograph when the patient is able .
