研究概览
简要总结
This study investigates if a new medical device, which injects contrast media and flushing solution into humans to increase the visibility of images taken of the human body for diagnostic purposes, is easier to handle, quicker and cheaper than an older injector.
详细描述
The study compares an investigational injection system (Centargo) for computed tomography (CT) to a currently marketed injection system (Stellant MP) in terms of efficiency, cost, performance and user satisfaction (Part 1). In addition, the reliability of the new injection system Centargo is tested (Part 2).
