CSF flow studies are performed using a variety of MRI techniques and are able to qualitatively assess and quantify pulsatile CSF flow. The most common technique used is time-resolved 2D phase-contrast MRI with velocity encoding. Note, when referring to CSF flow in the context of imaging we are referring to … See more Time-resolved 2D phase-contrast imaging with velocity encoding is the most widely used method and relies upon location-specific sequential application of a pair of phase encoding pulses in opposite directions.
