Brain uptake of [18F]flutemetamol [ Time Frame: Time zero equals the date of PET imaging. A follow-up phone call approximately 24 hours after the [18F]flutemetamol will be made to assess potential adverse events (AEs). ] [ Designated as safety issue: No ]
Determine the level of association between the quantitative estimates of brain uptake of [18F]flutemetamol and the quantitative immunohistochemical estimates of amyloid levels in biopsy samples obtained during shunt placement in patients who have NPH. The quantitative estimates of brain uptake of [18F]flutemetamol (SUVR) will be made from the analysis of PET images.

Positron Emission Tomography Imaging of Brain Amyloid in Normal Pressure Hydrocephalus
A Principal, Prospective, Open-label Biopsy Study to Validate Detection of Cerebral Cortical Amyloid With Flutemetamol (18F) Injection in NPH Subjects.

To determine the level of association between the quantitative estimates of brain uptake of [18F]flutemetamol and the quantitative immunohistochemical and histochemistry estimates of amyloid levels in frontal lobe biopsy samples obtained from subjects during shunt placement for NPH.
