Preparing for an MRI

Magnetic Resonance Imaging (MRI)

What is Magnetic Resonance Imaging (MRI) and how does it work?  back to top

Magnetic Resonance Imaging (MRI) is one of the most accurate methods of diagnostic imaging available today. MRI enables your physician to view the human body without the use of x-rays or invasive procedures and obtain precise diagnostic information. The following will explain everything you need to know about your exam.

MRI utilizes a strong magnetic field and radio frequency waves to construct a computer image. The image is then printed on a special film that is reviewed by a radiologist.

For some MRI procedures contrast media, commonly referred to as “dye”, is sometimes given intravenously during certain scans to provide the physicians with additional information.

Is a MRI for everyone?  back to top

Although MRI is an effective diagnostic tool, certain medical conditions will prevent individuals from having an MRI. Please inform your physician and our center personnel at the time of scheduling if you have either of the following:

  • Cardiac Pacemaker
  • Implantable Cardioverter Difibrillator (ICD)
  • Cochlear Ear Implant

Other certain medical conditions may prevent individuals from having an MRI. Please inform your physician and our center personnel at the time of scheduling if you have any of the following:

  • Metal fragments located in one or both eyes
  • Metal fragments or prosthesis within the body
  • Pregnancy
  • Certain type aneurysm clips
  • Other certain type of electrical or magnetic activated implants

It is very important that if you are pregnant or there is a possibility of pregnancy, or if you are breast feeding, that you inform your physician and the center personnel prior to your MRI.

If any of these conditions exist, your physician and/or the center radiologist will determine if you can be safely imaged or recommend an alternative diagnostic imaging procedure that can be safely performed for your condition.
