Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Portable semi-upright radiograph of the chest demonstrates lower lung volumes with resultant bronchovascular crowding . There is increased prominence of the right hilum , which was not clearly seen in the prior radiographs . The degree of bibasilar opacification has increased over the interim and may represent atelectasis versus pneumonia . There is engorgement of the pulmonary vessels , particularly in the left lung . An endotracheal tube is seen terminating 4 .5 cm from the carina . Right - sided internal jugular central venous catheter ends in the distal SVC .
    OUTPUT:
    
Interval increase in bibasilar opacities may represent atelectasis versus pneumonia . Engorged pulmonary vessels , particularly on the left lung field , may relate to pulmonary edema .
