Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A bedside AP radiograph of the chest shows a new endotracheal tube terminating no less than 4 cm above the carina . Compared to 4 .5 hours earlier , there has been marked worsening of alveolar pulmonary edema , now largely masking the peripheral nodular opacities likely representing disseminated infection . Small bilateral pleural effusions persist . There is no pnuemothorax . Marked widening of the cardiac silhouette is stable since admission and reflects the presence of pericardial effusion and cardiomegaly .
    OUTPUT:
    
1 . Worsening pulmonary edema superimposed on what is likely a disseminated infectious process . 2 . Stable pericardial effusion and cardiomegaly . 3 . The endotracheal tube is properly positioned .
