Brief summary
The purpose of this study is to examine the role of ShuntCheck and MR Imaging in evaluating the presence or absence of Shunt Obstruction in the patients of Hydrocephalus or Idiopathic Intracranial Hypertension (IIH) undergoing radionuclide test for suspected shunt obstruction. This is an exploratory study to determine how a non-invasive device can assist in detection of presence of flow in these patients.
Detailed description
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.

Patients with an indwelling shunt and clinical assessment strongly suggestive of shunt obstruction 3. Patients are candidates for shunt patency procedures in the elective extension
Exclusion criteria
1. Patients \<35 years of age 2. Patients with symptoms attributable to valve malfunction or shunt infection 3. Patients who need urgent shunt replacement and therefore cannot wait for the SHUNTCHECK evaluation of shunt patency. 4. Patients with edema or wound of skin overlying the shunt tissue. 5.
