    INPUT: Endotracheal tube tip terminates approximately 5 .5 cm from the carina . Orogastric tube tip terminates within the stomach . A percutaneous gastrostomy tube is noted , with balloon projecting over the region of the stomach . The heart size is normal . The aortic knob is calcified . The lung volumes are low . Hazy ill - defined opacity is noted in the right lung , primarily the right perihilar region , findings which could reflect asymmetric pulmonary edema though infection , aspiration , or hemorrhage is not excluded . No large pneumothorax is identified though a trace right pleural effusion may be present . Linear lucency through the posterior aspect of the right 1st rib is suggestive of a nondisplaced fracture .
    OUTPUT:
    
1 . Support lines and tubes are in standard positions . 2 . Hazy opacification primarily within the right perihilar region could reflect asymmetric pulmonary edema though aspiration , hemorrhage or infection is not excluded . 3 . Possible nondisplaced fracture of the right 1st rib .
