LGV flow velocity is clinically important to foresee esophageal varices development and rupture. But it is difficult to measure it's velocity exactly by echo or only phase contrast MRI (PC-MRI). To measure LGV flow velocity, 2D PC-MRI were set perpendicularly across vessel segments in the cross-sectional slice position determined from 3D selective visualized LGV using non-contrast-enhanced MRA with balanced steady-state free-precession sequence and time-spatial labeling inversion pulse. LGV flow velocity of all subjects could be measured exactly. This method is useful to measure LGV flow velocity.
