Which identifier should accompany radiographs?

• A. Patient name or ID number
• B. Hair color
• C. Eye color
• D. Favorite food

Answer: (A)

Accurate patient identification on radiographs is essential for ensuring the image belongs to the correct person and can be linked to the proper medical record for treatment planning and legal documentation. The best identifier is the patient’s name or ID number because it uniquely ties the image to that individual and supports traceability across encounters, dates, and procedures. Traits like hair color, eye color, or favorite food do not reliably distinguish one patient from another and are not suitable for clinical radiographs, as they can be shared by many people and aren’t part of the medical record. Including the correct ID prevents mix-ups, ensures accurate diagnosis and follow-up, and helps meet record-keeping and privacy requirements.
