    INPUT: Frontal and lateral views of the chest were obtained . A previously seen left - sided PICC has been removed in the interval . A tube / catheter projects over the upper abdomen .

There is no pleural effusion or pneumothorax . The cardiac and mediastinal silhouettes are stable , with the cardiac silhouette normal in size and the aorta calcified .
    OUTPUT:
