MRI

What to Expect During Your MRI

If it has been determined by your physician or the radiologist that your study requires the use of a contrast material (or dye), the technologist will perform the venipuncture and administer the contrast. This contrast does not contain Iodine, which many patients are allergic to.

The exam itself lasts for 30-60 minutes. You will be asked to lie down on a cushioned table. The table is moved into position within the large doughnut shaped magnet. The area being examined is placed in the center of the magnet to optimize the images. Because the magnet is very sensitive to motion you will be asked to keep very still. At all times you are able to speak with the technologist to keep he/she informed of your comfort and needs. You will hear a series of loud thumping noises as the scan is performed. Hearing protection will be provided, either with a music headset or with earplugs. Although outside music items (such as MP3 players) are not allowed, FM radio is available. You may also bring a CD of your choice.

After your exam, the MRI images will be sent to our PACS (picture archiving and communication system). A radiologist from the X-ray Professional Association at Concord Hospital will review and interpret your MRI scan.

What to Expect During Your MRI with Arthrogram 

In some instances, an arthrogram will be performed prior to the MRI.   An arthrogram is the injection of a contrast agent or radiology dye into the problem joint.  This examination provides additional detail regarding the interior of the joint.   You will be escorted to a changing area where lockers are provided for your belongings.  You may be asked to change into an exam gown and robe.  You will then be brought to a radiology procedure room.   Here the radiologist will explain the procedure, answer any questions, and have you sign a consent form.  Your skin will be cleansed with an antiseptic and the area will be numbed with a local anesthetic.   A needle will be placed in the joint space guided by an x-ray machine.  When the needle is in the correct place, the contrast material will be injected.   A number of x-ray images will be taken and you may be asked to move the affected joint.  This part of the procedure will take up to 30 minutes.  After the arthrogram procedure, you will be taken to the MRI scanner for the completion of your study.  The MRI will take up to 45 minutes.  Please plan on being in the office for up to 2 hours for completion of an MRI with arthrogram. 

What to Wear for Your MRI

• Gold, sterling silver and platinum jewelry (such as wedding bands) may be worn unless the jewelry is near the area being imaged.
• Watches and belts will always have to be removed.
• For women, most exams require that the bra is removed because of the underwire and hooks. Sports bras are recommended.
• Pants or shorts with buttons and zippers have to be removed for most (not all) exams. Sweat pants, pajama bottoms or other fabric only bottoms (without metallic eyelets from drawstrings) are recommended.

What NOT to Bring to Your MRI

• Cell phones, pagers, iPods, MP3 players, Walkmans or any other electronic device
• Credit cards, drivers license and any other card with a magnetic strip
• Loose change
• Bobby pins, safety pins or any other item with metallic pieces
• Any loose metallic items on clothing or body
• Glasses, hearing aids and items such as TENS Units will not be able to go into the exam room, but can be worn until just before entering the MRI room

Other Things to Note

• There are no restrictions in your use of medications or your diet prior to the MRI.
• If a sedative (such as Valium) has been prescribed for your exam, you MUST bring a driver with you. If you choose not to have one, please expect to stay at Concord Orthopaedics for at least 2 hours following your exam for your safety.
• If at the time of scheduling you forgot to inform us of a surgical procedure or of an injury to your eyes that included metal, please call 603-724-2318 prior to your exam. Otherwise, the MRI may be delayed.

If there are any questions or concerns prior to your MRI scan, please call the MRI department at 724-2318. Having all of the information and knowing what to expect with your exam will make your testing comfortable and easy.
