Nov 24, 2010 · Do I get a copy of the MRI scans? Yes, images are available to patients in both the public or private system. At private clinics, the images may be part of the overall price or they may be a small additional charge.
MRI stands for Magnetic Resonance Imaging. It is a painless diagnostic procedure that allows physicians to see detailed images of the internal structures of your body without using X-rays. It uses a large magnet, radio waves and a computer to produce images of your internal organs and structures.
MRI is a painless, non-invasive scan that produces high-resolution images of the inside of the body to assist in a medical diagnosis. MRI technology utilizes a strong magnetic field combined with radio waves to create detailed, cross-sectional images of internal organs and structures.
Magnetic resonance imaging (MRI) is done for many reasons. It is used to find problems such as tumours, bleeding, injury, blood vessel diseases, or infection. MRI also may be done to provide more information about a problem seen on an X-ray, ultrasound scan, or CT scan.

Magnetic resonance imaging (MRI) is a technique using magnets, radio waves, and a computer that produces images of soft tissues in the body, like muscles and organs. Unlike some other imaging tests, this type of scan does not use radiation.
An MRI scan is a noninvasive medical test that provides images of the soft tissues, like organs and muscles, within the body. The images are created using a magnetic field along with radio waves and a computer.
An MRI machine is big enough to fit around your entire body. Its tube-shaped magnets create a magnetic field that realigns the protons found in all the water molecules in your tissues.
Radio waves transmitted by the machine are what help create 3D images. They appear as slices, called cross-sections, and allow doctors to visualize each layer of tissue.
Your doctor may order an MRI with contrast. This means that prior to the scan, you will be given a contrast agent (sometimes called a “dye”) intravenously. This agent typically contains a metal called gadolinium.
When a contrast agent is in your body, it speeds up the proton activity and produces brighter, clearer images.
MRI is not used to diagnose things like broken bones. This is because bones do not contain much water, so the magnetic field and radio waves cannot make clear images.
Instead, MRI is used to visualize organs and other soft tissues. It can help diagnose a variety of health conditions throughout the body.
MRI of the brain and spinal cord can detect:
•brain aneurysms
•brain injury
•eye or ear issues
In general, you can expect your MRI to go something like this:
1.You will arrive at your appointment, change into a cotton or paper gown, and remove any metal objects (like jewelry or watches) from your body.
2.You will lie on the scanning table and be moved into the MRI machine. The hospital staff will be able to communicate with you through an intercom.
3.The machine will make beeping and clicking noises. They may be quite loud — up to 120 decibels, or louder than a chainsaw. The hospital staff may provide you with earplugs or other protection from the noise.
4.You will need to lay still for the duration of the scan. You may notice that the area of your body being scanned feels warm.
5.The scan will last between 20 and 90 minutes. The length of time depends on what part of the body is being scanned.
There isn’t much preparation involved with getting an MRI. You may take your medications and continue eating and drinking as you usually do.
If you are having an abdominal or pelvic MRI, you may need to fast for 5 or more hours before your scan.
Following your scan, you may wait to ensure the images are clear. If the radiographer needs additional images, you may need to go back into the MRI machine.
If everything looks good, you can get dressed and go home to wait for your results. MRIs are noninvasive, so there isn’t any necessary recovery time or aftercare.
Again, MRI machines do not emit radiation like X-ray or CT scans. That said, the magnets are extremely powerful in and around the machine.
It’s important to inform the hospital staff about any medical implants you have that contain metal. Likewise, you’ll need to remove any jewelry or other metal objects (steel, iron, etc.) from your body and clothing before entering the room with the machine.
Implants that may be affected include:
•pacemakers
•vagus nerve stimulators
•implantable cardioverter-defibrillators (ICDs)
MRI scans are generally safe.
Experts advise that pregnant people may need to avoid scans, particularly in the first trimester when a baby’s organs are forming.
Your images will be read by a radiologist or other doctor who is trained to interpret MRI scans. The report of that specialist’s findings will be forwarded to your doctor.
You will likely have a follow-up appointment with your doctor to discuss these results and any next steps.

What to Expect. Referrals. What We Do. Magnetic Resonance Imaging (MRI) is a non-invasive procedure used to take pictures of the inside of the body. With the use of very powerful magnets in conjunction with radio waves, MRI is able to produce an image that relies on the magnetic properties of atoms rather than radiation.

What is MRI & how does it work?
An MRI is a very useful tool for helping your doctors see images of the inside of your body, including tissue that can't be seen on a conventional x-ray. Before your exam, it's very important to fill out the safety screening form carefully.
