Safety Features on CT Contrast Injectors: Enhancing Patient Protection

April 24, 2017 | Evaluations & Guidance


During computed tomography (CT) studies, power injectors are routinely used to administer contrast media so that vasculature can be visualized. Though most studies are completed safely, the potential for serious harm cannot be ignored.

One significant risk is extravasation, the leakage of contrast medium out of the vein at the injection site, which can significantly damage the surrounding tissues. Another risk—one we believe may not be widely recognized for CT injectors—is air embolism, which has been fatal in some cases, and which appeared in the Top 10 health technology hazard list in our November 2008 issue.

It is generally accepted that following good clinical practice is the best way to reduce the incidence of problems. But these practices aren’t always enough—human error happens. A combination of good practices and effective safety features can go a long way toward keeping patients safe. All the products covered in this Evaluation have safeguards to help make contrast injection as risk-free as possible.

We’ve taken a close look at the safety features and functions of the following products:
