Magnetic Resonance Imaging (MRI) is an advanced diagnostic tool that is important for identifying and monitoring various medical conditions. Unlike X-rays or CT scans, MRI does not use radiation, making it a safe option for patients of all ages. An MRI also provides a clearer picture of soft tissues, joints, and internal organs than X-rays.
While most people are familiar with the concept of an MRI scan, many may not realize the different types of MRI machines available today and how they differ. With this knowledge, a patient may choose to schedule their MRI procedure with the type of machine that best suits their needs, whether it be Open MRI, Wide Bore MRI, or Standard Bore MRI.
How Does an MRI Work?
An MRI machine creates a magnetic field around the body that aligns the protons in our tissues. When radio waves are introduced, these protons absorb the energy and release it as signals. These signals are then detected by the MRI machine and processed into detailed images by a computer.
These highly detailed images help doctors identify abnormalities, tumors, or injuries that may not be visible through other imaging methods. It is especially useful for examining the brain, spinal cord, joints, and soft tissues, enabling early detection and appropriate interventions. Once diagnosed, patients can get a personalized treatment plan based on their condition and continually monitor that condition if needed with one or more follow-up scans.
EmergeOrtho – Coastal Region uses state-of-the-art MRI machines and imaging software, including Open MRI, Wide Bore and Standard Bore MRI units, to provide accurate and high-quality images. Our advanced technology ensures efficiency and patient comfort while obtaining precise diagnostic results. Whether detecting sports injuries or evaluating joint conditions, our MRI machines provide exceptional imaging capabilities to support effective medical care.
Types of MRI Machines
Different types of MRI machines can be used based on the specific needs of the patient, especially in orthopedics and spine diagnosis. Each type has its own advantages and is suitable for different patients, their preferences, and their situations.
Open MRI
An Open MRI is a type of MRI machine that uses an open-sided scanner instead of the traditional enclosed tube. This design significantly reduces feelings of claustrophobia, making it more comfortable for patients who experience anxiety in enclosed spaces.
The Open MRI unit pictured above is EmergeOrtho – Coastal Region’s newest Open MRI unit now available in the Porters Neck area of Wilmington, NC, the FujiFilm 1.2T Oasis Velocity Open MRI. With its weight limit higher than other types of MRI, wider table, and true open design, the Oasis Velocity Open MRI is a highly accessible and comfortable option for patients.
An Open MRI is also ideal for pediatric patients or other patients who may benefit from having a parent or guardian lying down next to them during the MRI scan for increased comfort.
Wide Bore MRI
A Wide Bore MRI machine will have an enclosed interior like a traditional MRI, with a slightly larger bore (usually 70cm) and a higher weight limit. The 1.5 GE Signa Voyager Wide Bore MRI unit pictured above is EmergeOrtho – Coastal Region’s newest mobile MRI unit and has a weight limit of 550 lbs; it is also equipped with advanced Air Recon DL software which cuts scan times down up to 1/3 of the typical scan time for a Wide Bore MRI.
Generally, a Wide Bore MRI is ideal for patients seeking the benefits of both increased comfort and efficiency.
Standard Bore MRI
A Standard Bore MRI machine is typically thought of as a traditional MRI. Standard Bore specifications range; the GE Medical 1.5 Tesla Magnet MRI at EmergeOrtho – Coastal Region in Wilmington on Shipyard Blvd. has a bore size of 60cm and a weight limit of 300 lbs.
Standard Bore MRI machines are favorable to patients due to their scan times which are typically faster while maintaining high image quality.
Contrast-Enhanced MRI
While each type of MRI machine serves the same overall function, other variables may take place during an MRI scan procedure depending on each patient’s needs, such as the injection of a contrast agent. An MRI with contrast involves using a contrast agent to enhance the visibility of certain tissues or blood vessels. The contrast agent is injected into the bloodstream before the scan, allowing the radiologist to better differentiate between normal and abnormal tissues.
This type of MRI is recommended by a patient’s care team on a case-by-case basis. An MRI referral will identify whether an MRI with contrast is necessary.
MRI Safety and Preparation
When undergoing an MRI scan, it’s important to prioritize safety and be properly prepared for the procedure. Here are some important considerations regarding MRI safety and preparation:
Safety Precautions During an MRI
MRI machines use magnets and radio waves to create detailed images. It’s crucial to follow safety precautions to ensure a safe and successful MRI experience. Patients must remove all metal objects, such as jewelry, watches, and clothing with metal zippers or buttons, as they can interfere with the magnetic field. Individuals with certain medical implants or devices, such as pacemakers or cochlear implants, may not be eligible for an MRI due to potential risks. Be sure to inform your healthcare provider of any implants or devices beforehand. View an example MRI screening form here for a full list of requirements.
Preparing for an MRI Scan
Before an MRI scan, follow specific instructions to ensure accurate results and minimize potential risks. Depending on the area being scanned, you may need to refrain from eating or drinking for a certain period before the procedure. It’s also important to inform your healthcare provider about any allergies, previous surgeries, or medical conditions you have. They will provide detailed instructions regarding medication use, as some medications may need to be temporarily discontinued before the scan.
What to Expect During the Procedure
During the MRI scan, you will be positioned on a movable table that slides into the MRI machine. You must lie still to ensure clear images. The machine may produce loud noises, so you may be offered the choice of wearing earplugs or headphones with music to minimize discomfort. The scanning process is painless, but some people may feel claustrophobic inside the machine. If you experience anxiety or discomfort, inform the technologist who will assist you.
The scan duration depends on the area being examined and specific protocols. On average, an MRI scan takes 30 to 60 minutes, but more complex scans or those involving multiple body parts may take longer. Your technologist will inform you about the estimated duration before the scan.
After the scan, a radiologist reviews the images, interprets the results, and provides a report to your healthcare provider, who will then discuss the findings with you and develop an appropriate treatment plan if necessary.
