Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Comparison is made to prior study from ___ . There is a right - sided central venous catheter with distal lead tip in the mid right atrium . This could be pulled back 3 - 4 cm for more optimal placement . There is an endotracheal tube whose distal tip is 7 cm above the carina at the level of the aortic knob , appropriately sited . The cardiac silhouette is upper limits of normal . There are airspace opacities bilaterally , most confluent in the left mid lung field . This may represent underlying infiltrate . There is also an infiltrate at the right base laterally , which appears stable . There are no signs for overt pulmonary edema . There are no pneumothoraces . The distal tip of the endotracheal tube is not included on the field of view of the study that cuts off the lung bases .
    OUTPUT:
    
1 . Right central venous catheter tip in right atrium and could be pulled back 3 - 4 cm . 2 . Bilateral opacities more confluent in the left lung .
