Digital right and left markers should be used to indicate the anatomic side imaged.

• A. True
• B. False
• C. Not important
• D. Optional

Answer: (B)

The side of the body shown on an image must be clearly and verifiably marked, and markers placed at the time of exposure are the reliable way to ensure this. While digital right/left overlays can be added after processing, they should not be the sole indicator of which side is imaged because they can be altered or misplaced. A physical left/right marker used during exposure stays with the original radiograph and provides a tamper-resistant, auditable indication of the anatomical side. Digital markers can supplement, but they do not replace the need for a real marker, so the statement is not correct.
