    INPUT: Single portable view of the chest . No prior available for comparison . Endotracheal tube is seen with tip approximately 4 cm from the carina , in appropriate position . Right - sided PICC line is seen with tip in the right brachiocephalic vein , relatively close to the superior SVC . Enteric tube seen with tip off the inferior field of view and the sideport is seen below the GE junction . There is dense retrocardiac opacity identified silhouetting the hemidiaphragm , which could be due to any combination of effusion , atelectasis , or consolidation . The lungs are otherwise grossly clear . The cardiomediastinal silhouette is notable for median sternotomy wires and mediastinal clips . Degenerative changes noted at the left shoulder with heterotopic ossification in the adjacent soft tissues .
    OUTPUT:
    
1 . Endotracheal tube in appropriate position . Right PICC line seen with tip likely in the distal right brachiocephalic vein , in close proximity to the upper SVC . 2 . Dense retrocardiac opacity which could be due to any combination of effusion , atelectasis , and / or infiltrate .
