Are shunts OK for MRI?

NHS GGC MRI safety policy for patients with shunts is as follows. If the shunt is known not to be a programmable shunt, then 1.5T and 3T MRI may safely proceed. If it is established that a shunt is a programmable device, then follow the instructions outlined in the instructions for use for that particular device.

Are Ommaya reservoir MRI compatible?

Once the Ommaya reservoir is placed, you’ll feel a small bump on your head where the reservoir is. You’ll likely need a CT scan or an MRI scan within a day of your surgery to make sure it’s correctly placed. If it needs to be adjusted, you may need a second procedure.

Is proGAV MRI compatible?

COMPATIBILITY WITH DIAGNOSTIC PROCEDURES The proGAV valve will not change when subjected to an MRI of 1.5 T or 3.0 T. All components are visible via X-ray. The provided catheters are MRI Safe.

Is an Ommaya reservoir a shunt?

An ommaya reservoir provides direct access to your cerebrospinal fluid (CSF). An ommaya reservoir, also called an ommaya shunt, is placed during surgery. A provider may suggest an ommaya reservoir if: You will need frequent administration of chemotherapy to treat cancer cells in the CSF.

What is an Ommaya reservoir used for?

An Ommaya Reservoir is a small, plastic device that is implanted in your brain. It allows your doctor to deliver medicine directly to the fluid around your brain and spinal cord. It also allows your doctor to take samples of the fluid around your spinal cord to test it.

What material are VP shunts made of?

The commonly used material from which the shunt catheters are made is silicone. This material is a surface where colonisation occurs. The traumatised tissue in the immediate vicinity of the implant, in the absence of a proper host defence mechanism, provides ideal conditions for colonisation by organisms.

Can magnets affect a VP shunt?

Patients implanted with magnetic externally programmable CSF shunt valves may have a risk of experiencing an unintended change in their valve setting when exposed to strong magnetic fields from external magnetic sources and implanted medical devices that use magnets.

How do you check if VP shunt is working?

By injecting a small volume of contrast dye or a radiotracer into the shunt reservoir, the flow of CSF through the catheters and valve can be measured. Shunt Tap is a diagnostic test to screen for infection and confirm that the shunt is still functioning.
