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
- 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.

The blood test should have been performed no more than 30 days prior to their exam. Patients should speak to their referring physician to make these arrangements as certain patients with the above conditions may not be able to receive the intravenous contrast associated with the MRI exam.
What should I expect during a MRI? back to top
- You may be asked to change into a clinic gown and escorted to the MRI room.
- A MRI technologist will assist you on to the padded exam table and position you for the procedure.
- During the procedure, you will need to lie as still as possible; movement can cause blurred images requiring the MRI technologist to repeat part of the procedure.
- You will hear knocking sounds during the procedure. Earplugs, headphones, or music will be provided for your comfort.
