The chest radiographs show a feeding tube within the stomach and a left upper extremity peripherally inserted central catheter (PICC) line with the tip located in the proximal superior vena cava (SVC). The cardiomedial silhouette is stable with no focal parenchymal opacities. There is minimal blunting of the left posterior costophrenic sulcus, suggestive of a small left pleural effusion.
