PY - 2020 DA - 2020/07/02 TI - Optimization of quantitative time-resolved 3D (4D) digital subtraction angiography in a porcine liver model JO - European Radiology Experimental SP - 37 VL - 4 IS - 1 AB - 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), a measure of contrast pulsatile strength, within the hepatic vasculature of an in vivo porcine model.
