MRI Safety Data for Active Facial Nerve Stimulation Implants

Phantom and patient data assess MRI safety for peripheral nerve field stimulation devices treating facial pain. The dataset includes results from in vitro phantom experiments and a single patient validation scan. The study was authored by figshare admin karger and last updated in April 2026.

Use Cases

• Analyze relationships between head specific absorption rate (SAR) and temperature rise at distal lead electrodes.
• Compare time-averaged positive radiofrequency magnetic field component (B1+rms) with heating at cranial coiling and implantable pulse generator locations.
• Validate safe fMRI sequence parameters, like T1w MPRAGE and BOLD, informed by phantom testing for in vivo application.
• Assess engagement of pain-related brain regions from BOLD fMRI data acquired during active stimulation in a patient.

Strengths

• Data validates safety under a critical 2°C temperature threshold at all monitored implant locations.
• Includes results from both controlled phantom experiments and a patient scan for methodological validation.

Limitations

• Patient validation is limited to a single case (n=1), restricting generalizability.
• The 3.5 MB size indicates a small dataset, likely containing documentation and summary results rather than raw data.
• Findings are specific to the tested device configuration and MRI sequences, not universally applicable.
