Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The patient is intubated . The endotracheal tube terminates approximately 2 cm above the carina . There is a right internal central jugular venous catheter terminating in the superior vena cava . The heart is probably normal in size , allowing for technique . The aortic arch is partly calcified . The lungs are essentially clear , perhaps with minimal left basilar atelectasis . Opacification of the left costophrenic sulcus makes a very small pleural effusion difficult to exclude , although doubted . There is no pneumothorax .
    OUTPUT:
    
Status post endotracheal intubation . No definite evidence of acute disease .
