Proactive Air Management in CT Power Injections: A Comprehensive Approach to Reducing Air Embolization

Objective: Venous air embolism as a complication of contrast media administration from power injection systems in CT is found to occur 7%-55% patients, impacting patient safety, diagnostic image quality, workflow efficiency, and radiographer satisfaction. This study reviews the challenges associated with reactive management approaches employed on contemporary systems, proposes novel approach using proactive methods, compares impact injected volumes under simulated clinical use. Methods: Injected three were measured use via custom trap fixture. Two approaches, while new system implemented proposed approach. Results: The significantly less (average 0.005 mL ± 0.006 maximum 0.017 mL) when compared two (averages 0.130 0.082 0.106 0.094 maximums 0.259 0.311 mL, respectively) (p <; 0.05). images taken static dynamic 0.1 bubbles inside vascular phantom, both which clearly visible. Additionally, bubble was shown introduce artifacts similar those observed clinically. Conclusion: Comparison show that tested employing approaches. Significance: results indicate could reduce prevalence observable, potentially artifact-inducing, venous contrast-enhanced procedures.
