Dynamic contrast enhanced imaging of the liver using 3D spiral offers a greatly increased ability to visualize the different enhancement sub-phases. In this abstract, we propose to use a high frame rate reconstruction using the same data to derive signal enhancement curves of the aorta, portal vein and other territories. These are used to obtain optimal temporal windows for a second reconstruction of particular sub-phases.
