[Dual echo steady state (dess) pulse sequence in the evaluation of brain cerebrospinal fluid flow disturbances].

The authors present their experience with the Dual Echo Steady State pulse sequence used to evaluate brain cerebrospinal fluid (CSF) flow by low-field magnetic resonance imaging. Normal and pathologic CSF flow patterns are discussed. The capacities of the technique as an auxiliary tool to have additional diagnostic information via visualization of flows in the brain CSF pathways are shown.
