Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: In comparison to the prior radiograph performed 3 hours earlier , there has been an interval increase in the diffuse interstitial opacities and redistribution , perhaps slightly worse at the right lung base . Along with underlying moderate cardiomegaly , these findings together suggest pulmonary edema . There is no substantial pleural effusion or pneumothorax . A linear radiopaque line along the periphery of the right hemithorax represents a fold from the patient 's gown , as lung markings are seen lateral to this line . No acute osseous abnormalities identified .
    OUTPUT:
    
Worsening interstitial pulmonary edema and redistribution compared to the prior radiograph performed 3 hours earlier .
