Piercings and X-Ray Imaging: Safety, Artifacts, and Communication Protocols

Body piercings are common; their interaction with radiographic imaging is manageable with proper communication and technique.

Physics of Piercing Artifacts

Metallic jewelry (steel, titanium, gold, niobium): High atomic number → intense photoelectric absorption → radiopaque streaks/artifacts obscuring underlying anatomy.
Non-metallic (glass, acrylic, PTFE, bioplast): Radiolucent — minimal artifact.
Size/Geometry: Larger gauge, dangling jewelry = larger artifact volume.

Anatomic Considerations by Piercing Site

Piercing Site	Imaging Affected	Artifact Severity	Typical Action
Ear (lobe, helix, tragus, conch)	Skull, facial bones, cervical spine, dental	High (skull/dental)	Remove for head/neck imaging
Nose (nostril, septum, bridge)	Facial bones, sinuses, skull base	High	Remove for facial/sinus imaging
Lip/Labret/Monroe/Medusa	Mandible, dental, cervical	High (dental)	Remove for dental/jaw imaging
Tongue	Cervical spine, soft tissue neck	Moderate	Remove for neck imaging
Nipple	Chest, sternum, ribs	Moderate	Remove for chest imaging
Navel	Abdomen, pelvis, lumbar spine	Low–Moderate	Remove for abdominal/pelvic imaging
Genital	Pelvis, hips, femurs	Low–Moderate	Remove for pelvic imaging
Dermal/Microdermal (any site)	Local area	Variable (anchor visible)	Remove if in field of view

Clinical Decision Framework

Patient informs tech: "I have piercings at [sites]."
Tech assesses: Is jewelry in/adjacent to FOV (Field of View)? Is it ferromagnetic (MRI safety)?
If in FOV: Request removal. Provide clean container, gloves, mirror.
If removal impossible (fresh <8–12 wks, embedded, patient refusal):
- Reposition patient to move jewelry out of FOV.
- Use angled projections.
- Lead shielding over jewelry only (reduces scatter, not primary beam artifact).
- Note limitation on report: "Piercing artifact may obscure [anatomy]."
New piercings: If removal risks closure/infection, discuss with radiologist. May accept limited study or alternative imaging (US, MRI if non-ferromagnetic).

MRI-Specific Concerns

Ferromagnetic jewelry: Projectile risk, torque, heating — MUST REMOVE.
Non-ferromagnetic (Ti, niobium, glass): Safe at 1.5T/3T but may cause susceptibility artifact.
Screening: MRI safety questionnaire + verbal confirmation + wand/ferromagnetic detector.

Radiation Protection

Jewelry does not increase patient dose significantly (scatter minimal).
Lead apron/shield for gonads/thyroid per standard protocol — independent of jewelry.

Best Practices

Pre-appointment reminder: "Remove all jewelry in area to be imaged."
Facility provides piercing removal kits (sterile gloves, hemostats, containers).
Document: "Piercings removed: [sites]" or "Piercings retained: [sites] — artifact noted."
Patient education: "Your piercing can hide a fracture. Removing it ensures we see everything."

Piercings are manageable with communication. The radiologist's goal: diagnostic images. The patient's goal: keep piercing intact. Usually both achievable.
