    INPUT: A portable frontal chest radiograph again demonstrates a right PICC terminating at the cavoatrial junction . There has been interval placement of a nasogastric tube , which courses below the diaphragm and off the inferior edge of the image . The cardiomediastinal silhouette is normal . Lung volumes are slightly lower compared to prior , with exaggeration of the cardiac silhouette and bronchovascular crowding . Allowing for this , there is no focal consolidation , pleural effusion , or pneumothorax . The visualized upper abdomen is unremarkable .
    OUTPUT:
