Frequently Asked Questions
Do I need a referral for an MRI scan?
Yes. Your doctor must order the MRI scan for you. He/She will schedule a time that is most convenient for you.
Why not just get an x-ray?
An MRI is a more comprehensive test of bones and tissues. An MRI shows in-depth the area of the anatomy in question.
What is the main difference between X-Ray and MRI?
Aside from the fact that MRI does not use radiation to obtain images, the biggest difference is that MRI can "see through" bone and define fluid-filled soft-tissue, while x-rays can only define bone.
What is the difference between an Open MRI and a Closed MRI?
The term open has to do with the actual structure of the MRI’s gantry. The open gantry is generally open on all four
sides where the closed is a cylinder shape with no view out. Open MRI’s are great for claustrophobic and larger patients.
They are also more conducive to patients looking for a more comfortable experience.
My doctor says Open MRI’s are not as good as Closed MRI’s
All of our Open MRI centers are accredited by the American College of Radiology. This means our images meet the same
standards as Closed MRI’s. You should always choose an accredited facility.
How far into the MRI scanner will I be?
How far into the scanner you go depends on what part of your body is being scanned. If you are having your foot, ankle,
knee, leg, or lumbar spine scanned then you will be going feet first. In most cases your head will not even be under the
magnet. All other scans, such as head, cervical spine, thoracic spine, or shoulders you will be required to go head first.
Is MRI safe?
There are no known effects from having a MRI. MRI’s use radio frequencies and magnetic fields to obtain images. As oppose
to a CAT scan or X-Ray which uses ionizing radiation.
Can I eat or drink before I have my MRI?
Yes, eat and drink as you normally would prior to your exam.
What should I wear?
Wear loose fitting comfortable clothes. You will want to avoid clothes with zippers or snaps. Gowns are also available.
How long is the exam?
The length of the exam depends on the anatomy that is being scanned. In most cases scans are approximately 35 to 45
minutes. Exams requiring contrast are approximately 20 minutes longer.
Can I bring someone with me while I'm having my scan done?
You may bring someone over the age of thirteen into the scanner room with you. You will both be screened for any metal in
or on your body and will be asked to remove any jewelry or articles that are not magnetically safe. Once cleared from a
medical and safety standpoint, they will be allowed to accompany you into the scan room.
Why does the MRI scanner make so much noise?
The tapping and knocking noise you hear during your scan is caused by magnetic coils that switch on and off during the
scan. These coils measure the signal coming from your body in order to make the images that are used for your diagnosis.
Because these coils are switched on and off rapidly, they vibrate and cause the noise you hear.
Will I be able to listen to music while having my scan done?
Yes. Our centers are equipped with a radio system that allows you to listen to music while having your scan. You may also
bring a favorite CD to listen to while the exam is taking place.
What types of metal are not allowed in the MRI scanner?
No metal is allowed in the MRI scanner, but, there are exceptions. Joint implants, bone screws and plates are allowed into the MRI scanner, provided the implants have been in the body at least four to six weeks. Other implants, such as vascular
aneurysm clips or pacemakers are not permitted in the MRI room. Metals such as jewelry, watches, earrings, dentures, partial
dental plates, hairpins, hearing aids, keys, coins, or other loose metal should be removed before going in the scanner room.
If you have any questions regarding metals, please speak with your doctor or the MRI technologist prior to your exam.
Will I need an injection during the procedure?
Not everyone requires an injection for their MRI procedure. Injections are given only if your physician or the radiologist interpreting your scan feels that an injection is necessary. Injections are generally used to enhance tissue in a surgical
area.
If an injection is needed, what is injected and how is it given?
If an injection is required to complete your scan, a contrast agent called Gadolinium is used. This contrast causes the
tissues and blood vessels of the body to be seen more clearly than with conventional, non-contrasted MRI. Gadolinium is
injected into the body through veins in your arm or hand.
Is it safe to have an MRI if I'm pregnant?
MRI is considered a safe exam and does not require the use of radiation. However, conclusive studies regarding potential
hazard to a pregnancy have not been established. If an MRI is ordered during the first trimester (12 weeks) of pregnancy,
discuss the study with your physician and ask him or her to explain the benefits and risks associated with this exam.
How soon after the scan is completed will the results be available?
Results are faxed to your doctor usually within 24 hours after your exam. If there are prior studies to the area in
question, the radiologist will want to make a comparison, which may take additional time.
