A real‐time, 20‐Hz, one‐dimensional MR velocity imaging technique is described. A two‐dimensional RF pulse excites a 3‐cm diameter column. Velocity maps are formed from the phase difference between successive flow encoded and compensated acquisitions. A three‐point subtraction variation provides reduced sensitivity to static spins.
