MR Neurogram: Preparation and Safety Tips

Before Your Examination

A UCSF Precision Spine and Peripheral Nerve Center radiological technician will contact you by telephone before your examination. During this call, he/she will review patient safety and examination preparation and aftercare tips.

Because MR neurography involves a strong magnetic field, some patients cannot undergo this type of examination. If you have any of the conditions or devices (implanted) listed, please alert our staff and technicians. The radiology staff can let you know whether you can have the examination or if the exam can be modified.


Allergy to iodine or gadolinium
History of diabetes
History of kidney problems
History as a metal worker
Shrapnel or bullet wound(s)
Skin tattoos
Other conditions or implants

*If you are claustrophobic, your doctor may prescribe an oral medication for you to take for your MR neurography appointment

Devices (Implants)

Aneurysm clip(s)
Artificial heart valve(s)
Cochlear implant(s)
Dorsal column stimulator(s)
Exposure of metal fragments to your eye(s)

Patient Safety Tips

  • Please leave your valuables at home (e.g. jewelry)
  • If you prefer not to change into hospital attire (e.g. gown), please wear cotton clothing without metal zippers, hooks, or buttons.
  • Tell us if you need an interpreter. We'd be pleased to arrange this service for you.
  • Bring a list of your current medications with dosage information.

Preparation Guidelines

  • Few preparations are necessary for an MR neurography procedure. You can go about your daily routine and take any medication you usually take, unless you are instructed otherwise.
  • If your doctor has prescribed medication for claustrophobia, be sure to arrange for a responsible adult to drive you home.
  • Please arrive 30 minutes before your scheduled exam time.
  • Register at the reception desk and complete an MR neurography screening form.
  • If you are wearing clothing with metal fasteners or metallic design, you must change into hospital attire (e.g. gown, robe). You are provided a locker to secure your belongings.
  • A technician verifies your identification and scheduled examination. During this time, a thorough MR neurography screening is performed to check for conditions or devices (implanted) that may contraindicate magnetic resonance neurography. If a contraindication exists, the technician or radiologist explains the situation and provides you with alternative information.
  • Feel free to ask questions or tell us additional information.
