    • Dilute iodinated contrast with sterile saline or water in a 50/50 ratio
  • Long Bone Protocol
    • Includes humerus, forearm, femur, and lower leg/extremity
    • Cover entire long bone in the field of view and surrounding soft tissues to the skin surface
    • Axial reformats perpendicular to the long bone diaphysis
