Implication

Retrospective study reveals that low-dose chest parameters and tailored collimation reduce radiation exposure in pediatric foreign body ingestion, suggesting safer imaging protocols.

Key Points

To evaluate how different collimation strategies and radiographic exposure parameters impact radiation dose in pediatric patients with suspected foreign body ingestion.
Retrospectively analyzed 221 radiographs from 183 pediatric patients (median age 2.8 years, interquartile range 1.5–5.5; 112 males, 71 females) imaged between September 2019 and April 2025.
Categorized radiographic protocols into neck–upper abdomen, extended collimation including the pelvis (both using chest exposure parameters), and abdomen-only views.
Assessed foreign body presence, anatomical location, dose-area product (DAP), and estimated effective dose across protocols.
Foreign bodies were detected in 55.7% of radiographs, localized mostly in the stomach (59.4%), with coins (31.7%), button batteries (13.8%), and magnets (12.2%) being most common.
Dose-area products were comparable between standard neck-to-upper-abdomen and extended neck-to-pelvis collimation, but were significantly higher for abdomen-only imaging (P < 0.001).
Effective dose increased with extended pelvic collimation (P < 0.05) and was highest for abdomen-only radiographs (0.053 mSv [IQR 0.034–0.086 mSv], P < 0.001).
