Curves between the energy window width (x-axis) and the normalized SNR (y-axis). Each of the three contrast agents has its optimal energy window width for the maximum SNR: for 0.9% iodine solution (black), the optimal width is 3.9keV; for 1.5% barium solution (red), the optimal width is 5.4keV; and for 0.5% Gadolinium solution (blue), the optimal width is 6.299keV.
