Magnetic Resonance Imaging (MRI)

Magnetic Resonance Imaging (MRI)
Magnetic Resonance Imaging (MRI) is a safe, non-invasive exam that uses powerful magnets and advanced technology to create highly detailed images of the body. Unlike X-ray or CT imaging, MRI does not use radiation, making it an excellent tool for evaluating a wide range of conditions.

MRI is commonly used to diagnose and evaluate:

  • Stroke, aneurysms, and neurologic conditions
  • Joint injuries, including rotator cuff and meniscal tears
  • Degenerative spine conditions, such as disc herniation
  • Cancers affecting organs, bones, and soft tissues

Preparation & After Your Exam

In most cases, no special preparation is required. You may continue your normal daily activities after your MRI unless sedation is used. If sedation is needed, you will require someone to drive you home and should avoid driving for the remainder of the day.

If you experience claustrophobia, speak with your physician in advance—options are available to help ensure your comfort.

Important Safety Information

Because MRI uses a strong magnetic field, it’s essential to inform our team if you have:

  • A pacemaker, defibrillator, or artificial heart valve
  • Metal implants such as plates, pins, clips, or surgical hardware
  • Aneurysm clips or inner ear implants
  • An intrauterine device (IUD)
  • Permanent eyeliner (tattoo)
  • Metal fragments in your body or eyes
  • A history of metal work or exposure
  • Any implanted stimulator device

Joint replacements (after appropriate healing) and most dental work are typically safe for MRI.

What to Expect

MRI exams typically take between 20–45 minutes, depending on the area being imaged. During the scan:

  • You will be asked to remove all metal objects, including jewelry and accessories
  • You will lie still while images are acquired
  • You may hear rhythmic knocking or thumping sounds—this is normal, and ear protection is provided
  • Music may be available at select locations for added comfort

Some exams require a contrast agent to enhance image quality. If needed, this will be administered safely by our trained team.

Comfort & Care

We understand that MRI exams can feel confining for some patients. If needed, your physician may prescribe medication or arrange for monitored sedation in advance. Our goal is to ensure a comfortable, supportive experience from start to finish.

Our Approach to Imaging Quality

Our imaging centers utilize advanced MRI technology designed to deliver superior image quality and diagnostic accuracy. While “open MRI” systems are available in some settings, they often produce lower-resolution images. We prioritize high-quality imaging to provide the most precise and reliable results for your care.
