Performance of Centargo: A Novel Piston-Based Injection System for High Throughput in CE CT

Area of Science:

• Medical Imaging Technology
• Radiology Devices
• CT Injection Systems

Background:

• Current CT injection systems require optimization for efficiency.
• User satisfaction and injector performance are critical in clinical settings.
• Evaluating new devices like the MEDRAD Centargo is essential for advancing CT imaging.

Purpose of the Study:

• To compare the MEDRAD Centargo CT Injection System to the MEDRAD Stellant CT Injection System.
• Assess differences in efficiency, injector performance, and user satisfaction.
• Determine the potential benefits of the Centargo system in clinical practice.

Main Methods:

• A two-phase study involving 425 patients across two sites.
• Phase one: Randomized comparison of Stellant and Centargo, recording setup, disassembly, and patient changeover times.
• Phase two: Observational assessment of Centargo usability via radiographer questionnaires.

Main Results:

• Centargo showed statistically significant faster patient changeover times (15.4s vs 53.7s, p < 0.001).
• Projected efficiency gains with Centargo ranged from 40-63% based on patient throughput modeling.
• Both systems demonstrated high usability scores, with no safety issues or performance failures reported.

Conclusions:

• The MEDRAD Centargo CT Injection System offers improved efficiency over the Stellant system.
• Centargo maintains high injector performance and user satisfaction.
• Centargo represents a potential advancement in CT injection technology.
