In this study, newly developed wireless intracranial pressure (ICP) monitoring devices were evaluated under MR imaging conditions at 3.0T. Significant image distortions were observed near the devices due to magnetic susceptibility effects. Temperature changes near the ICP devices, during MR scanning (with 16.65W of RF power), were directly measured using fiber optic thermal sensors. Of three devices, a smaller ICP device with titanium casing showed the lowest temperature change. Future ICP device developments will focus on minimizing image distortions and ensuring proper function and safety with the active device.
