A computed tomography (CT) power injector (also named pressure injector) is used to deliver contrast agents during CT imaging procedures with high-flow, high-volume, fixed-rate injection at relatively high pressures. The use of power injectors allows precise administration of contrast agent to obtain consistent high quality CT images. A dual-head CT power injector permits loading of contrast and saline onto the same injector. Contrast injection systems manage injector protocol data, improve patient safety, and workflow efficiency. When combined with pressure monitoring systems and hardware to prevent extravasation (accidental leakage of IV material into the surrounding tissue) these CT injectors can simultaneously mitigate risk.
