Parkinson's Disease and MRI

Font Size

MRI, or magnetic resonance imaging, is a test that produces very clear pictures, or images, of the human body without the use of X-rays. Instead, MRI uses a large magnet, radio waves, and a computer to produce these images.

Is a MRI Exam Safe for Parkinson's Disease?

Yes. The MRI exam poses no risk to the average person if appropriate safety guidelines are followed. But, if you have a deep brainstimulator to treat your Parkinson's disease, talk to your doctor before having an MRI since the stimulator(s) may need to be turned off.

Some conditions may make a MRI exam inadvisable. Tell your doctor if you have any of the following conditions:

How Long Does the MRI Exam Take?

Allow 1 1/2 hours for your MRI exam. In most cases, the procedure takes 45 to 60 minutes, during which several dozen images may be obtained.

What Should I Expect Before a MRI?

Personal items such as your watch, wallet, including any credit cards with magnetic strips (they will be erased by the magnet), and jewelry should be left at home if possible, or removed prior to the MRI scan. Secured lockers are available to store personal possessions.

What Should I Expect During the MRI?

As the MRI scan begins, you will hear the equipment making a variety of banging, clanging and muffled thumping sound that will last for several minutes. None of them are anything other than annoying. Other than the sound, you should experience no unusual sensations during the scanning.

Certain MRI exams require an injection of a contrast material. This helps identify certain anatomic structures on the scan images.

Please feel free to ask questions. Tell the technologist or the doctor if you have any concerns.

What Should I Expect After the MRI?

  • Your doctor will discuss the test results with you.
  • Generally, you can resume your usual activities and normal diet immediately.
