What it is

An MRI (Magnetic Resonance Imaging) is a safe, painless, non-invasive procedure that does not use radiation. Instead, this technology uses strong magnetic fields and high frequency radio waves to produce a three dimensional image. Your physician may order an MRI to evaluate structures within your body not visible by routine x-rays.

Arlington Orthopedic Associates has three latest-technology MRI machines, each of which allows for a much more comfortable exam, especially for claustrophobic patients. Your physician will recommend using whichever machine will be most beneficial in diagnosing your problem.

Open MRI
Short Bore MRI
Detailed Extremity MRI

What to expect

An MRI requires no preparation, however, please arrive 15 minutes prior to your scheduled exam time in order to complete all appropriate paperwork. The length of the appointment depends on the type of scan, but you should generally allow 60 minutes.

To expedite the exam process, wear comfortable clothing that is free of metal. Shorts or a gown will be provided if this is not possible.

The radiology technician will ask you some simple questions, such as whether you’ve had surgery before and if you have any metal clips or devices in your body. The answers to these questions may or may not disqualify you from having the test. Be sure to mention if you have any of the following:

Cardiac pacemaker
Vascular/ Aneurysm clips
Brain aneurysm clips
Insulin/ medicine pumps
Fractured bones with rods, screws, etc.
Metal slivers in any area of the body
Shrapnel
Implant stimulator/ neurotransmitter
Joint replacement less than 8 weeks old
Permanent prosthesis
Eye/Ear/Brain implants

Due to the strong magnetic fields surrounding the MRI machine, the following items must be removed before entering the room in order to protect the machine and your belongings:

Hearing aids
Jewelry
Credit/Debit cards
Watch
Keys
Purse/wallet

Most often there are no injections, but if your physician is looking for something in particular, the radiologist may put a small amount of contrast material into a joint or area to be examined.

For most examinations you simply lie still for about 30 to 45 minutes and the test is done. Severe moving while the MRI test is in use may cause the test to be repeated, thus delaying your examination time.

Once your scan is complete, the image will be reviewed by a radiologist and the results of your scan will be discussed with your physician. This process generally takes 24-28 hours.
