Adjustable Suppression of Water Signal in the Background in Subtractionless First-Pass Peripheral Angiography with Dual-Echo Dixon Imaging

Holger Eggers¹, Tim Leiner²

In contrast to the established subtraction approach, the recently proposed subtractionless approach to first-pass peripheral angiography based on dual-echo Dixon imaging removes only the fat signal, but not the water signal from the background. In this work, an image processing method is described that allows separating the water signal in the background from the enhanced water signal in the vessels and thus tailoring the extent of background signal remaining in particular in the maximum intensity projections calculated for the visualization of the vasculature to individual preferences.
