Stellant® Dual CT Injector

MEDRAD's Stellant D Is the Right Choice for Advanced CT Clinical Applications

Stellant D CT injector is a full-featured, dual syringe injection system that enables clinicians to perform the most critical CT contrast exams.

Saline Before and After Contrast

Because it is a dedicated, dual-head CT injection system, Stellant D allows you programming flexibility, including the exclusive ability to use saline before AND after contrast. From Saline test injection to timing boluses, Stellant D expands the number of protocols available to you with a single CT injector. Check out these sample CT injector protocols >>

Stellant D also provides clinical advantages from contrast savings to better diagnostic images.

Saline Flush

Stellant D introduces saline flush capability for CT imaging sites that need to produce optimal images using the most advanced clinical applications, such as those for Cardiac Angio and CTA.

Stellant D also provides intuitive automation and convenience features that can lead to reduced setup times and shortened overall scan times.

Saline Advantage

MEDRAD's Stellant D Injection System brings saline flush capability to your CT procedures. The addition of saline to contrast injections has proven clinical advantages for imaging professionals. Here is some additional information about saline use in CT.

What can saline flush do?

Used as a "bolus chaser", saline creates a tighter bolus.
Independent research indicates that saline flush may reduce image artifacts in thoracic CT applications (1)

Saline Flush

bulletComplements Multidetector CT (MDCT)
bulletCreates tight bolus
bulletAllows clinicians to perform complex protocols like CTA, Cardiac CT
bulletEnables precisely-timed contrast delivery (pure arterial phase)
bulletPromotes efficient contrast use (1)
bulletAllows sequential injections of contrast & saline
bulletReduces artifacts and improves attenuation curve in thoracic CT (1)

Right Place, Right Time

Saline flush helps get contrast to the right place at the right time. The attenuation curve at the top demonstrates the theoretical ideal enhancement, putting the exact volume of contrast into the area of interest at the time of the scan. Achieving this ideal attenuation curve would require an impractically complicated, ideal bolus.
The illustration at the bottom shows that optimized enhancement, approximating the ideal, is possible with saline flush. Saline helps create a practically applicable, biphasic bolus that optimizes the contrast in the area of interest during the scan (2,3).
