MRI (Magnetic Resonance Imaging)

Magnetic Resonance Imaging uses a super conductive electromagnet, radio waves and sophisticated computer software to generate and enhance images. The result is an unprecedented view of internal organs, body structure and systems. Morris County Hospital utilizes high-quality hardware and software to provide doctors with the detailed images they need to make an accurate diagnosis. MRI provides excellent images without radiation exposure.

What to expect during your magnetic resonance exam

The technologist will constantly be in touch with you via intercom. You’ll lie down on the MRI table, which will move into the scanner. During the exam, you may feel a slight vibration and hear a series of rhythmic knocking or hammering sounds. This is all normal. Some MRI exams require the injection of a contrast dye, which assists the Radiologist in obtaining optimal images to make a diagnosis. Most exams take about an hour.

Preparation for your MRI

Patients with pacemakers, neurostimulators or other implantable electronic metallic devices should never enter an MRI suite without first being cleared by the MRI technologist or the radiologist in charge.

If you have previously had any metal in—or removed from—your eyes, you may have to undergo eye x-rays.

If your exam is ordered with MRI contrast you will need Lab work prior to the exam being done, to check the function of your kidney’s.

You’ll also need to remove all metal, jewelry, snaps, zippers, pens, pocket knives, pagers, cell phones, guns, ammunition and the like. Anyone accompanying you into the suite must remove all loose metallic objects, as well as billfolds and purses.

Any questions regarding MRI safety should be directed to the technologist or radiologist in charge for the day.

Patients who are breastfeeding and whose procedure will require the ingestion of a contrast agent for their MRI exam will need to express milk before the exam, as the contrast agent will remain in the milk for 24 hours.
