ShuntCheck Versus Radionuclide in Evaluating Shunt Function in Symptomatic NPH Patients (SCNPH)
The purpose of this study is to compare the accuracy of ShuntCheck (SC) and ShuntCheck plus Micro-Pumper (SC+MP) to radionuclide shunt patency testing (SPS) in evaluating shunt function in patients with adult hydrocephalus (AH) implanted with ventriculoperitoneal (VP) shunts when shunt obstruction is suspected and a diagnostic procedure such as radionuclide shunt patency testing (SPS) is required.

|Official Title:||A Double- Blinded Comparison of the Accuracy of ShuntCheck, a Non-Invasive Device, to Radionuclide Shunt Patency Test in Evaluating Shunt Function in Patients With Adult Hydrocephalus With Possible Shunt Obstruction|
- Sensitivity and specificity of ShuntCheck vs SPS [ Time Frame: Day 1 ] [ Designated as safety issue: No ]
The primary efficacy objective is the sensitivity and specificity of the ShuntCheck test.
The performance of ShuntCheck test will be compared to the radionuclide scanning done on the day of ShuntCheck administration. Primary efficacy of the SC and SC+MP test will be determined by comparing SC and SC+MP performance to results of radionuclide scanning according to a standard 2 x 2 table, with a Positive test result defined as evidence of shunt obstruction.
|Study Start Date:||June 2011|
|Estimated Study Completion Date:||April 2013|
|Estimated Primary Completion Date:||March 2013 (Final data collection date for primary outcome measure)|
Device: ShuntCheck test
The primary objective is to demonstrate that the accuracy of SC and SC+MP for determining whether a VP shunt is patent or obstructed is statistically no different than the accuracy of the accepted standard test, radionuclide shunt patency study, when performed simultaneously.
A secondary objective is to determine SC and SC+MP results in the presence of possible partial obstruction, which defined as subjects with radionuclide clearance measured by T1/2 of 8 to 10 minutes.
A secondary objective is to compare ShuntCheck flow rate results to simultaneous radionuclide clearance as measured by T1/2. A secondary objective is to demonstrate that ShuntCheck flow rate results are statistically equivalent to simultaneous radionuclide clearance measured by T1/2
