This paper summarizes our experience of exploiting a Dual Echo Steady State (DESS) pulse sequence for the fast qualitative assessment of cerebrospinal fluid (CSF) flow dynamics at the aqueduct of Sylvius and Monro's foramina levels of the brain liquor pathways using a low-field magnetic resonance imager. Normal and pathologic CSF flow patterns are discussed. The capabilities of the described method as an effective extra tool for deriving the additional diagnostic information via visualization of flow voids in the brain CSF pathways are shown.
