DualFlow provides users of MEDRAD's Stellant D CT Injector with the ability to illuminate both the right and left sides of the heart simultaneously. With patented technology, Stellant D provides the ability to inject contrast agent and saline at the same time and the resulting clinical applications are powerful.
Don't take our word for it. Hundreds of clinicians are already using Stellant D with DualFlow to image the heart in illuminating detail. Recent work by one of Europe's leading CT Radiologists is highlighted in a new case study.

The new DualFlow feature of the Stellant D helps you utilize new high-speed scanning capabilities for Cardiac CT. When imaging the heart, a long drawn-out attenuation peak is not optimal. Precise timing is critical and Stellant D with DualFlow helps you achieve the optimum attenuation peak at the precise time it is needed for enhanced image quality.
An independent study1 shows that a three-phase injection provides superior enhancement uniformity in both the right and left side of the heart. This is accomplished by delivering a first phase of contrast only, followed by a second phase of contrast and saline at a 50 / 50 ratio, and finally a third phase, saline flush, to ensure the optimal amount of contrast reaches the heart.
The secret behind DualFlow is simultaneous motion of the contrast and saline pistons. This technology allows injection of both fluids at the same time in a measured ratio. The result is closely matched attenuation levels in both sides of the heart so that artifacts are reduced and image quality is improved. These high-quality images are then more suitable for 3D enhancement software because the program has real data from which to create the rendering, not extrapolations.
