Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The patient is markedly rotated which limits assessment . The endotracheal tube is positioned with its tip approximately 2 cm above the carina , this is improved compared to the prior study . Bilateral diffuse airspace opacities are slightly improved when compared to the prior study . Again this may reflect pulmonary edema versus infection . The cardiomediastinal contour is unchanged . No pleural effusion or pneumothorax seen . A right internal jugular catheter terminates in the distal SVC .
    OUTPUT:
    
Improved positioning of the endotracheal tube . Slight interval improvement in the bilateral airspace opacities .
