St Vincent's Clinic Medical Imaging & Nuclear Medicine

CSF Shunt Study

A CSF Shunt study is used to evaluate ventricular shunt patency and function.

What will happen when you have your CSF Shunt Study

There are two main parts to your CSF Shunt Study:

  1. A small injection of a radioactive tracer will be injected into the shunt reservoir. This injection is sterile, has no side effects and   shouldn't interfere with any medication you are taking. After the injection images will be taken for approximately 45 minutes. You will then be asked to wait 1 hour before the next set of images. During this time you may eat and drink as normal.
  2. On your return to the Nuclear Medicine department you will be asked to lie on the scanning table and more images will be  acquired. This will take approximately 30 minutes. You may be required to return a further 1-2 hours after this set of images, and possibly undertake a further 30min of images. During the wait you may eat and drink as normal.

What you need to do and how to prepare for the test

You will not be required to undress for the scan. The scan is performed with the Gamma Camera close to your body but you do not go through a “tunnel”
