The test usually takes 30 to 60 minutes but can take as long as 2 hours.
A single scan may take from a few seconds to 3 or 4 minutes. You may be asked to hold your breath during short scans. Depending on the size of the area being scanned and how many images are taken, the whole procedure will take 15 to 90 minutes.
The procedure is painless. You don't feel the magnetic field or radio waves, and there are no moving parts around you. During the MRI scan, the internal part of the magnet produces repetitive tapping, thumping and other noises. You might be given earplugs or have music playing to help block the noise.
The scan may last between 15 and 90 minutes, depending on how many images of the brain are needed.
A brain MRI usually takes between 30 to 60 minutes to complete.
After your MRI scan, a radiologist will analyze the images. The radiologist will send a signed report to your primary healthcare provider, who will share the results with you. The report is usually ready for your healthcare provider within one or two days.
Since the MRI machines are magnets, it is best to not apply deodorants, antiperspirants, perfumes, or body lotions before the examination. These items contain metals that might interfere with the magnetic field inside the MRI machine and cause you to have distorted images and wrong results.
If you are having an MRI scan that does not require you to follow commands, you may be allowed to fall asleep. You should clarify this with your radiologist before the procedure begins.
Generally, MRIs under anesthesia are performed under sedation, although sometimes they are performed under general anesthesia. Sedation is characterized as being in a state between relaxed and very sleepy, but not quite unconscious.
Brain MRIs usually take between 12 and 20 minutes to complete, whereas a breast MRI can take up to 45 minutes. MRIs take a long time to complete because they take many hundreds of images of your tissue in slices. They then build this up into a three-dimensional representation that doctors can study.
The average cost of an MRI can range anywhere from $400 to $12,000, depending on the place of service, health insurance, location, extra medications, the provider, and body part scanned. Health insurance typically covers authorized MRIs.
As a result of the foreign body's ease of movement in the strong magnetic field at this period, your vision is seriously threatened. Because of this, radiologists advise keeping your eyes closed throughout an MRI to protect them.
You will be in constant communication with the MRI technicians and you can stop the scan at any time. We have a fan in case you get warm, blankets in case you are cool and bolstering pillows to help you stay comfortable during a long scan.
An MRI scan will show a detailed image of your brain, spinal cord, nerve tissue, and more. A neurologist would order an MRI (magnetic resonance imaging) of your brain if they suspect something is wrong, if they are diagnosing an issue, or if they want to monitor the development or treatment of an injury.
They can talk with you and be there to support you during and after the examination. They can also drive you home if you have sedative medicine during the examination. If you do take sedative medication, you cannot drive yourself.
If you need to cough or get an itch, tell them and they can get you out, or give you a short break between sequences. Then you are moved out of the machine, released, have your plastic tube removed and can go home.
Can a subject wear deodorant for an MRI scan? It is recommended to refrain from wearing any powder, perfumes, deodorant and/or lotions on your underarms and chest area prior to the procedure. This is to prevent the possibility of localized burns because these items may have metal in them.
In most cases, a family member or friend may enter the MRI room with you and stay with you throughout your exam. If the situation allows, they may even hold your hand or pat you on the knees so that you know that they are there with you.
Gadobenate is a gadolinium-based contrast agent (GBCA). Gadobenate is given by injection before an MRI scan to help find problems in the brain, spine, and other parts of your body. This medicine is to be used only by or under the direct supervision of a doctor.
It's also best to avoid wearing makeup, nail polish, hair products, sunscreen and antiperspirants, as these items could contain metal particles. If you wear glasses, you will need to remove them when it's time for the scan.
You will not be able to have breakfast the morning of your surgery. You can brush your teeth in the morning, just be sure to spit the water out!
Things to remember
Unless you're told otherwise, you can shower and wash your hair the morning of your MRI. Don't use any hair products (such as hair spray or hair gel). Don't wear any metal objects. Remove all jewelry, including body piercings.
You will be asked to remove any clothing containing metal and all jewelry. You will be provided metal free clothing to change into such as gown, shorts or pants.
