We confirmed that 2D beam excitation presaturation-pulse (hereafter Beam Sat pulse) can saturate the vessels selectively and visualized hemodynamics in brain and liver. Although Beam Sat can visualize portal vein and hepatic artery, right hepatic artery (RHA) cannot visualize clearly because T1 relaxation of saturated blood magnetizations is short. In this study, 2D excitation pulse was used as IR pulse (hereafter Beam IR pulse), and we showed that the Beam IR pulse can clearly visualize a flow phantom and RHA of healthy volunteers.
