MRI

We offer state-of-the-art MRI scans at Atrium Health Floyd and Harbin Clinic. Our scanners use the latest technology, including an open-concept machine that creates high-definition images without the enclosed space.

What is an MRI?

An MRI (magnetic resonance imaging) is an imaging test that shows tissue and organs in detail. It creates pictures using a strong magnetic field and radio waves.

Types of MRI

MRI machines can have various designs and magnet strengths. Scanners that use stronger magnets create more detailed images.

Your provider will recommend a certain type of MRI based on your needs. Common types of MRI include:

Traditional MRI

A traditional MRI machine looks like a large, round tube with a hole in the middle (like a donut). You lie down on a table that slides into the middle of the machine.

Open MRI

An open MRI machine has an innovative design that eliminates the feeling of being enclosed by the scanner. The machine is more open on the sides, rather than surrounding you like a traditional MRI.

It helps you feel more comfortable during the scan. It can also accommodate people with obesity or claustrophobia.

Breast MRI

Breast MRI is an advanced breast imaging technique. It creates detailed pictures of breast tissue that help identify breast cancer early.

An MRI shows breast abnormalities that other imaging tests can’t detect. Your provider may recommend a breast MRI if you have dense breast tissue or face a high risk of breast cancer. They may also use MRI to learn more about signs of cancer seen on a mammogram (breast X-ray).

Cardiac MRI

A cardiac MRI creates still and moving pictures of your heart and major blood vessels. Your provider may use a cardiac MRI to check your heart health and diagnose problems such as:

• Cardiac tumors, an abnormal growth in your heart
• Congenital heart defects, which are structural abnormalities present at birth
• Coronary artery disease, when blood vessels in your heart become narrowed or blocked
• Heart attack damage, caused when blood flow to your heart stops
• Heart valve problems, such as a valve that doesn’t open or close properly
• Pericarditis, a swelling of the membrane around your heart

MRI uses and benefits

Your provider may request an MRI to help accurately diagnose problems throughout your body. An MRI can provide more information about abnormalities found on other imaging tests, such as X-rays or CT scans. It can also help your provider plan your treatment, including guiding surgery.

MRI doesn’t use ionizing radiation, unlike many other imaging methods. This means it doesn’t carry any risk of causing cancer. It’s a safe imaging test for people of all ages.

What to expect with MRI

You’ll have an MRI in a special imaging room. The scan can take anywhere from 20–90 minutes, depending on the images requested by your provider.

Some MRI scans require contrast dye, a special dye that helps create clearer images. If you need contrast, you’ll receive an intravenous (IV) injection before the scan.

Preparing for an MRI

You’ll change into a dressing gown and remove any jewelry. You’ll lie down on a table that slides into the middle of the machine when you’re ready for the scan to start.

An imaging technologist will give you pillows, blankets and ear protection to keep you as comfortable as possible during the scan. They’ll use special equipment, such as cushions, wedges or coils, to position the part of your body that needs imaging.

During an MRI

You’ll be able to hear and talk to the technologist during the scan. They’ll be running the machine from another room separated from you by a window.

You’ll need to remain very still to prevent images from becoming blurry. The technologist will tell you if there are breaks in imaging when you can move slightly.

The machine creates loud beeping and clicking noises during the scan. Your ear protection will help reduce the noise. You may also choose to listen to music through your ear protection.

After an MRI

You can resume your daily activities after an MRI. If you received contrast, make sure you drink lots of fluids throughout the day.

Your provider will share your MRI results within a few days. They’ll discuss any abnormalities with you and recommend next steps as needed.

MRI test risks and side effects

An MRI is a generally safe, noninvasive imaging test. Because the machine creates a strong magnetic field, it’s important to leave all metal and magnetizable objects outside the testing room. As a result, people with medical implants containing iron, such as pacemakers, insulin pumps and deep brain stimulators, can’t undergo an MRI.

The loud sounds produced by the MRI machine may cause discomfort or headache. The machine can also cause feelings of claustrophobia, where anxiety develops from being in a small, enclosed space. Tell the technologist if you feel like you need to get out of the scanner at any point.

Contrast dye may cause side effects, such as headache or nausea. In rare cases, it can cause a serious allergic reaction. Contrast dye can also affect your kidney health if you have an existing kidney condition.
