A new velocity imaging pulse sequence is evaluated by incorporating velocity phase encoding into the multiband simultaneous multi-slice EPI sequence. Six simultaneous images at different levels through the brain were acquired in time series at 100ms TR frame rate to measure CSF, brain motion and arterial velocities without cardiac gating and without combining signals recorded in different cardiac cycles. The technique can be further extended with greater slice coverage for 3D spatial maps in each time frame.
