    INPUT: A portable semi upright frontal chest radiograph demonstrates a left PICC which appears to terminate in the upper right atrium , although this may be related to low lung volumes . If desired , this can be pulled back approximately 2 .0 cm to terminate in the low SVC . The remainder of the exam is largely unchanged , with slightly lower lung volumes resulting in increased prominence of the cardiac silhouette and bronchovascular crowding . There is no focal consolidation , pleural effusion , or pneumothorax . The visualized upper abdomen is unremarkable .
    OUTPUT:
