Magnetic Resonance Imaging (MRI)

 

preparation-instructions

 

Magnetic resonance imaging, also known as MRI, uses powerful magnets, radio waves and computer technology to produce images of the inside of the body. MRI images provide exceptional detail of virtually all internal structures including organs, bones and soft tissues. MRI is most often used to diagnose neurological and musculoskeletal conditions.

What to Expect

Due to the strong magnets used in MRI machines, metal objects are not permitted in the MRI suite. You will be screened for metal objects including wearable accessories and medical devices. You may be given a gown to wear. The technologist will position you on the table, which then slides into a large upright circle. Once the MRI machine is running, you will hear clicking and knocking noises, which are completely normal.

An MRI exam consists of several sequences of images, during which you must remain as still as possible in order to avoid blurry images. If necessary, you may move in between sequences. The entire exam usually takes 30-45 minutes, depending on the part of the body being imaged. You can have someone stay with you during the exam, and you will also be able to communicate with the technologist throughout the exam via an intercom.

Our 1.5T Hi-Field Open MRI system is uniquely designed to accommodate all patients, including those who suffer claustrophobia or are above average size, up to 448 lbs. Although most patients do not experience claustrophobia in our Open MRI machine, please make arrangements with your physician prior to your imaging appointment if you feel you will need anti-anxiety medication.

Depending on the body part being imaged or the reason for your exam, you may receive contrast material as part of your exam. The contrast material used is called Gadolinium, which is given through an IV in your arm. It helps radiologists to more clearly visualize certain structures. It is given through an IV in your arm.

The results of your MRI exam are communicated to your referring provider 1-2 business days after your exam. If you have questions about your results, you are encouraged to speak with your referring provider, who can discuss your results in detail with you.

Some types of MRI exams require special preparation. Please check preparation instructions for your specific type of exam prior to your appointment day.

Risks

  • Be sure to tell the doctor or the technologist if you have any implanted medical devices, which may contain metal parts.
  • Allergic reactions to contrast material are rare, but can occur. Inform your doctor if you have a history of heart disease, asthma, diabetes, kidney disease or thyroid problems as these conditions may increase the risk of an allergic reaction.

Benefits

  • MRI images provide exceptional detail using a noninvasive imaging technique that does not utilize radiation.
