A member asked:

What's the chance (percentage) that an mri will change the settings on a codman hakim programmable vp shunt? can anything else change it?

Very high: Right after MRI you should have it reprogrammed to intended setting. Any strong magnetic field can alter the setting.

Good : The programmable shunt should be reprogrammed after exposure to a highly magnetic field such as mri.

High: The codman hakin programmable vp shunt does not have the newer "locks" like the codman certas or the sophysa that prevent changes in a high magnetic field like an mri. In fact, neurosurgeons are trained to be prepared to re-program the vp shunt any time the patient has an MRI scan. Any time these shunts are near a high magnetic field, there is a risk that the shunt will change its setting.
