Optimization of quantitative time-resolved 3D (4D) digital subtraction angiography in a porcine liver model
BACKGROUND: Time-resolved three-dimensional digital subtraction angiography (4D-DSA) can be used to quantify blood velocity. Contrast pulsatility, a major discriminant on 4D-DSA, is yet to be optimized. We investigated the effects of different imaging and injection parameters on sideband ratio (SBR)...
