In that procedure, a plastic tube must be inserted into the aorta and coronary artery openings.
Contrast is injected directly into the coronary arteries.
With EBA, the contrast is injected into a vein in the arm, with no internal tubes involved. The scanner takes images with the contrast and we can then reconstruct three dimensional pictures to look for narrowings in the coronary arteries. The white paper describes the technique and its indications, and provides some images from studies obtained at LifeScore.
