Magnetic Resonance Imaging (MRI)

Magnetic resonance imaging (or MRI) is one of the most comprehensive methods doctors and specialists use to assess the health of a patient. Our radiology department has invested in the latest MRI technology and MRI advances, giving our patients and their loved ones access to state-of-the-art diagnostics as part of their treatment at RWJBarnabas Health facilities in New Jersey.

How Does It Work?

MRI machines use a combination of radio waves, magnetic fields and powerful computer technology to create vivid images of the interior human body. During these tests, patients lie down and are inserted into a large tube that generates its own magnetic field. The MRI technology records how emitted radio waves interact with the field and processes those interactions with computer technology to generate images of inside the patient's body.

Patients can expect these tests to take anywhere from 30 minutes to an hour. They can eat, drink and take medications normally beforehand. Your doctor and radiologist will walk you through any further instructions before or during your appointment.

Do You Have Concerns?

The MRI machine can be intimidating for some patients, especially those who suffer from claustrophobia. In these cases, a doctor may be able to provide a sedative to calm the patient during their MRI.

Your doctor and radiologist will also discuss avoiding any interaction with metal during the test. Because the MRI uses magnets, it is critical that patients remove jewelry and other items that contain metal. If you have a pacemaker or another implant that contains metal, speak with your doctor before your MRI appointment.
