Brief Summary:
The purpose of this project is to assess the utility of a new magnetic resonance technique called magnetic resonance elastography (MRE) in the non-invasive diagnosis of normal pressure hydrocephalus. The investigators hypothesize that MRE produces a unique imaging signature for hydrocephalus that distinguishes the disease from the normal (non-hydrocephalic) but atrophied brain, a distinction not possible with conventional MR imaging studies that are presently available.

Arm Intervention/treatment
Experimental: MRE Device: MRE

Primary Outcome Measures :
  1. Mean shear modulus [ Time Frame: 15 Years ]
    The primary outcome measure will be mean shear modulus determined from pre-operative (and pre-drain placement) MRE in patients who demonstrate clinical improvement with trial CSF drainage versus patients who do not demonstrate improvement.

Secondary Outcome Measures :
  1. Pre-operative (and pre-drain placement) shear modulus in the experimental group will be compared with various assessments of clinical improvement after VP shunting. [ Time Frame: 15 Years ]
    Secondary outcomes will compare pre- and post-drain MRE shear moduli with ventricular size and intracranial pressure.
