Proactive Air Management in CT Power Injections: A Comprehensive Approach to Reducing Air Embolization
Prevention of air injection in contrast-enhanced Computed Tomography (CT) is an important topic. This work reviews air management approaches of contemporary power injectors, proposes a novel air management approach that is more proactive, and analyzes the injected air volumes under simulated clinical use. This proactive approach focuses on technology advances for air management prior to the injection, instead of simply monitoring air sensors during the injection. Results demonstrate a successful reduction in the amount of injected air under simulated use, which could translate in practice to fewer imaging artifacts and fewer workflow disruptions... Read more
