Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The patient is intubated . The endotracheal tube terminates approximately 5 cm above the carina . An orogastric tube terminates in the stomach . The heart is normal in size . The aortic arch is calcified . The mediastinal and hilar contours are otherwise unremarkable . The extreme left costophrenic sulcus is partly excluded , but there is no evidence for pneumothorax or pleural effusion . There is patchy left basilar opacity which is most likely to represent minor atelectasis . Two small apparent nodular densities project over the left mid lung and may be artifactual or potentially could represent true lung nodules , however . There is no pleural effusion or pneumothorax . Gallstones project over the right upper quadrant of the abdomen .
    OUTPUT:
    
1 . Satisfactory positioning of endotracheal tube . 2 . Questionable small nodular densities projecting over the left mid lung . Short - term repeat radiographs are recommended to see whether these may persist . 3 . Cholelithiasis .
