Dynamic phase-contrast MRI techniques by use of implemented FLASH through-plane sequence, positioned perpendicularly to the cerebral aqueduct enables the precise measurement of CSF flow parameters by “Segment” software in both experimental and control groups. Phase-contrast MRI CSF flow quantification within cerebral aqueduct may facilitate the establishing of the communicant hydrocephalus diagnosis, but also may enable to accurately differentiate communicant hydrocephalus from other entities, which correlates with the results of some other similar investigations^14,15.

Shapes of characteristic curves of net flow, average and maximal velocity were distinctively different between the observed groups, providing the easier distinction of the communicant hydrocephalus.

The evidently larger cross-sectional area of cerebral aqueduct in communicant hydrocephalus may appear as a predictive feature in a future, leaving the space to be potentially proven by some novel CSF flow measurement techniques¹⁶.
