Development of a user-friendly calculator for a pediatric split-bolus polytrauma computed tomography protocol.

Area of Science:

• Radiology
• Medical Imaging
• Pediatric Imaging

Background:

• Pediatric polytrauma computed tomography (CT) requires precise protocols to balance image quality, radiation dose, and workflow efficiency.
• Current methods for setting pediatric CT protocols can be time-consuming and may not consistently optimize contrast and timing parameters.

Purpose of the Study:

• To develop and present a user-friendly calculator for optimizing pediatric split-bolus polytrauma CT protocols.
• To reduce radiation dose and improve workflow efficiency in pediatric CT imaging while maintaining optimal image quality.

Main Methods:

• A calculator was designed using Google Sheets, accessible via QR code.
• The calculator computes essential parameters including contrast media volume, saline volume, injection flow rate, and injection timing based on patient weight.
• The protocol incorporates a mixed arterial and venous phase for comprehensive imaging.

Main Results:

• The calculator provides rapid computation of all necessary parameters for a pediatric split-bolus polytrauma CT protocol.
• It facilitates efficient workflow and aims to minimize radiation exposure in pediatric patients.
• The tool is adaptable for various clinical contexts beyond polytrauma, such as oncological, infectious, and vascular imaging.

Conclusions:

• The developed calculator offers a practical solution for optimizing pediatric CT protocols, enhancing both efficiency and safety.
• Its accessibility and ease of use make it a valuable tool for radiologists and technicians.
• The calculator's applicability extends to diverse pediatric imaging scenarios, demonstrating its versatility.
