Enhanced Image Quality
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.
An independent study¹ shows that a three-phase injection provides 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.
As an isotonic solution, saline is an accepted standard of care as a safe and effective IV maintenance product that is used in all hospitals around the world. When combined with saline, the structure of the contrast media is not altered, only the concentration. 1 Sablayrolles, J-L, “Cardiac CT: Experience from Daily Practice”, Advanced CT, Aug 2004: 4-10.
