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.
