This study aims to correlate findings of ShuntCheck and MRI with the Radionuclide patency study. Patients will be enrolled if they have Hydrocephalus or IIH, present with symptoms of shunt obstruction and will need to undergo shunt patency test and an MRI along with standard of care radionuclide study. The ShuntCheck study will be conducted in a clinic, doctor's office or in an emergency room by the treating physician or by trained health care professionals.
Also, patients who are found with shunt obstruction as diagnosed by Radionuclide study will undergo shunt revision and the findings of the study will be correlated with operative findings. Post Shunt replacement patients who also receive adjustable valve will be evaluated with shunt Check, before and after adjustment of valves to detect changes in flow as detected by shunt check.
This is an exploratory study to determine how a non-invasive device can assist in detection of presence of flow in these patients.
Approximately 20 subjects will be enrolled in a single site in this proof of concept, physician sponsored study. An approved, commercial device will be available to the site prior to start of the study.

Experimental: ShuntCheck measure
All patients will have ShuntCheck measurements along with radionuclide shunt patency testing.
Device: Shunt flow detection
Shunt flow detection based upon ShuntCheck results compared to radionuclide test results
- Exploratory Evaluation of the Utility of ShuntCheck in detection of ShuntFlow in patients admitted with potential shunt obstruction [ Time Frame: Pre and post shunt revision surgery ]
- To assess any adverse events that arise from conducting ShuntCheck test To assess the cost effectiveness of ShuntCheck screening upon completion of the study [ Time Frame: Pre and post shunt revision surgery ]
