Magnetic Resonance Imaging

What you need to know about MRI scans

MRI uses magnetism, radio waves and a computer to create cross-sectional images of structures within your body. The high image resolution is so detailed that radiologists can detect tiny changes within the specific area that was scanned.

Trained and experienced hospital MRI technologists conduct the tests at various Atlantic Health System imaging and MRI centers. And all of our radiologists are board-certified and have advanced fellowship training in interpreting MRI reports.

How to prepare for an MRI

• Wear loose-fitting clothing that doesn’t have any metal fasteners. You may be asked to wear a gown during the MRI scan.
• Guidelines about eating and drinking before an MRI vary for different types of scans. Get specific instructions from the doctor who is ordering your test.

• Women should tell their physician and the MRI technologist if you are breastfeeding or if there is any chance you may be pregnant.

• If you have anxiety or claustrophobia (fear of narrow spaces), ask your doctor to prescribe a mild sedative before the exam. This will help you relax. We offer a wide-bore MRI machine at many locations. A lot of our patients with claustrophobia find relief with this wider MRI machine.
• Infants and young children may need to be sedated to be sure they don’t move during the MRI exam. At Atlantic Health System, a physician or nurse specializing in giving sedation to children will be available during the exam to ensure your child’s safety. We’ll give you special instructions on how to prepare your child for the sedation.
• Leave metal objects at home or remove them before your exam. This includes hearing aids, jewelry, eyeglasses, dentures and hair clips.
• Foreign elements in your body can affect the MRI scan. An X-ray may be needed before the exam if there is any doubt about the presence of a foreign object. We’ll ask questions about your medical history and any previous surgeries. Tell the technologist if you have:
  • An artificial joint
  • Embedded shrapnel, bullets or other pieces of metal
  • Medical or electronic implants
  • Tattoos
  • Tooth fillings, braces or metal implants
• To avoid delays, bring a written copy of the MRI order provided by your doctor.
• Bring your medical device card if you have any implants.

MRI results

A board-certified radiologist will closely examine and interpret your MRI images. They’ll send a signed report to your primary care physician or the doctor who referred you for testing. Then your doctor will discuss the results with you.

MRI services vary by location. Be sure to confirm the exact location when making the appointment.
