    INPUT: The left costophrenic angle is excluded on this study . The tip of a new NG tube is not definitively visualized but appears to terminate below the diaphragm with its side hole likely above the level of the diaphragm , possibly within a hiatal hernia seen as a retrocardiac opacity . Heart size and cardiomediastinal contours are normal . Lungs are clear without focal consolidation , pleural effusion , or pneumothorax .
    OUTPUT:
    
1 . NG tube poorly visualized but likely terminates below the diaphragm with side hole above the diaphragm , possibly within a hiatal hernia . 2 . No focal consolidation . The left costophrenic angle is not imaged .
