  Purpose

The idea is to assess the predictive value of flow magnetic resonance imaging (flow MRI) for patient suffering normal pressure hydrocephalus (NPH) planned for surgery. By now, the depletive lumbar puncture is the best test assessing the efficacy of a forthcoming surgery. The idea is to demonstrate that flow MRI can be as effective as lumbar puncture in term of predictive value of surgery response.

In that way, cerebrospinal fluid (CSF) dynamics are evaluated by a single non invasive examination. CSF flow is measured at the Sylvius' aqueduct, cervical, arachnoid space and 4th ventricle levels.

Arms Assigned Interventions
Experimental: Normal pressure hydrocephalus
Hydrocephalus patients planned for shunting surgery. They will undergo clinical and imaging examinations at day 1, 3 months and 1 year after their surgery.
Other: clinical and imaging examinations

Quantitative CSF flow study was performed by 2D phase-contrast velocity-encoded cine MRI (repetition/echo time, 15/7 ms; field of view = 140 x 140 mm²; matrix size = 256 x 128, flip angle = 25 degrees,one excitation, slice thickness = 5 mm). Cerebrospinal fluid flow was measured with a velocity-encoding value of 10-20 cm/s. Peripheral gating was used to cover the entire cardiac cycle with retrospective cardiac synchronization of 32 quantitative flow-encoded images per cycle.

Clinical examination consists in neuropsychological assessment (including mini mental state examination test and Bradley's scale) as well as Hakim's triad evaluation
