Button batteries and typical swallowed foreign bodies can be differentiated in high-resolution X-Rays

Area of Science:

• Medical Imaging
• Radiology
• Pediatric Foreign Body Ingestion

Background:

• Button battery ingestions are a growing concern, particularly in children, due to their common presence in household items.
• These batteries pose significant risks of severe aerodigestive tract complications if ingested or aspirated.
• Distinguishing button batteries from other foreign bodies is crucial for appropriate medical management.

Purpose of the Study:

• To analyze specific radiographic identifiers of button batteries and similar esophageal foreign bodies.
• To evaluate the effectiveness of high-resolution X-ray scans in differentiating these objects.

Main Methods:

• In vitro high-resolution X-ray scans (33.3 lp/mm) of button batteries (CR2032, LR44, LR1130) and similar radio-opaque objects were performed.
• Porcine esophageal preparations were used to simulate realistic conditions.
• A comparative analysis of digital radiographic images was conducted.

Main Results:

• High-resolution scans revealed previously undescribed internal structures of button batteries.
• Four key features—edge properties, internal structures, size, and 0°/90° scan differences—enabled differentiation from other foreign bodies.
• The study successfully identified specific radiographic markers for button batteries.

Conclusions:

• Improved radiographic resolution, contrast, and dynamics enhance the identification of esophageal foreign bodies.
• Diagnostic reliability in distinguishing high-risk ingestions is increased, supporting clinical triage.
• Advanced digital image analysis and radiographic technology can improve button battery detection and reduce complications.
