When a bipolar readout gradient is used, increasing the velocity of flowing spins leads to more fat-water signal misallocations (incorrect mapping of water signal into the fat image.) Water images (b) and fat images (c) from a flow phantom experiment at 3.0T show the increasing signal misallocations as the flow increases from 0 to 12 mL/s through a tube containing a narrowing. The arrow in (a) shows the direction of flow. Note that the region of misallocated signal artifact in the fat image increases in both area and intensity as the flow increases.
