Clinical Impact
The models demonstrated reproducible performance across seven tertiary hospitals, with institution-wise AUCs ranging from 0.867 to 0.912 for intussusception and 0.832 to 0.850 for splenomegaly. Locked external test set results confirmed 0.818 AUC for intussusception and 0.806 for splenomegaly, indicating strong potential for real-world application.
Performance varied by body weight, with reduced sensitivity in infants <10kg (AUC 0.834 for intussusception, 0.782 for splenomegaly) but maintained high performance in children weighing 10-30kg (AUCs >0.89 for intussusception, >0.85 for splenomegaly). This highlights the need for further optimization for the smallest patients.
These AI models can serve as adjunctive tools for early detection and triage of intussusception and splenomegaly on pediatric abdominal radiographs, especially in emergency and resource-limited settings where specialist ultrasonography is not readily available. Prospective validation is warranted to confirm their impact on diagnostic workflows and patient outcomes.

Enhanced Triage in Resource-Limited Settings
Scenario:
In a rural clinic with limited access to pediatric ultrasound, a child presents with non-specific abdominal pain. An AI-powered abdominal radiograph analysis quickly flags a potential intussusception with 0.881 AUC confidence, prompting an urgent referral to a regional hospital for definitive diagnosis and treatment, significantly reducing diagnostic delay.
Outcome:
This early detection capability can transform pediatric emergency care, enabling timely intervention and potentially preventing severe complications like bowel ischemia and perforation. The model's robustness across different body weights (10-30kg showed 0.901-0.898 AUC for intussusception) further enhances its utility in diverse patient populations.
