What should you do if a radiograph shows a metallic artifact obscuring anatomy?

• A. Remove metallic object if possible, re-take with proper shielding or repositioning, and document the reason for retake.
• B. Ignore; artifacts don't affect diagnosis.
• C. Delete image and reuse film.
• D. Increase exposure to overcome artifact.

Answer: (A)

Metallic artifacts occur when a metal item in or on the patient intersects the X-ray beam, creating areas that obscure anatomy and potentially mimic or hide findings. The appropriate action is to remove the metallic item if possible and safe, then re-take the image with the beam aimed to avoid the artifact or with a better positional setup. This often means asking the patient to remove jewelry, dentures, earrings, or other metal objects, and adjusting the patient’s position or projection so the anatomy of interest is clear. Always apply the ALARA principle and avoid increasing exposure to “overcome” the artifact, since higher dose does not guarantee artifact removal and only adds unnecessary radiation. If the object cannot be removed, optimize technique through alternative projections or shielding and acknowledge the limitation in the record. Documentation should note what was removed, how the projection was adjusted, the reason for the retake, and any shielding or positioning changes, ensuring a clear and traceable quality record.
