Computed tomography of pediatric abdominal trauma: optimizing utilization and enhancing diagnostic interpretation

Area of Science:

• Radiology
• Pediatric Surgery
• Emergency Medicine

Background:

• Abdominal trauma is a significant cause of mortality in pediatric patients, accounting for 25% of major trauma cases.
• Computed tomography (CT) is the primary imaging modality for evaluating abdominal injuries in stable pediatric patients.

Purpose of the Study:

• To review pediatric-specific CT protocols for blunt abdominal trauma.
• To discuss strategies for reducing radiation exposure in pediatric CT scans.
• To highlight the updated American Association for the Surgery of Trauma Organ Injury Scale (AAST OIS) and its application in pediatric abdominal trauma management.

Main Methods:

• Review of current literature and guidelines on pediatric abdominal trauma imaging.
• Description of optimized CT protocols for pediatric patients.
• Explanation of the AAST OIS, including the 2018 update.
• Inclusion of illustrative CT images and an interpretation algorithm.

Main Results:

• Specific CT protocols tailored for pediatric blunt abdominal trauma are essential for accurate diagnosis.
• Radiation dose reduction techniques are crucial in pediatric imaging.
• The AAST OIS provides a standardized method for grading abdominal injuries, aiding in management decisions.
• Comparison of pediatric versus adult injury grading and management is discussed.

Conclusions:

• Optimized CT protocols and adherence to updated injury grading scales improve the management of pediatric abdominal trauma.
• Minimizing radiation exposure while maintaining diagnostic accuracy is a key consideration in pediatric CT.
• This review serves as a practical guide for radiology residents managing pediatric abdominal trauma cases.
