Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The image quality is somewhat limited by motion artifact during image acquisition . Right - sided dual - lumen central venous catheter is again noted , with the tip in the region of the cavoatrial junction . Diffuse alveolar opacities are seen bilaterally , which appears slightly worse than on the prior examination . It is difficult to assess for significant pleural effusion , but layering effusions are likely present . Cardiac silhouette is somewhat indistinct given technique , though probably unchanged .
    OUTPUT:
    
Slight worsening of pulmonary edema compared to the prior radiograph from 3 days previous . Overall morphology is very similar to the torso CT examination performed earlier on the same day .
