Innovations for Magnetic Resonance Imaging (MRI) Technology

Latest in Innovations for MRI Technology

Advancements in MRI Technology

Today’s MRI technology is built on decades of research on magnetic resonance, which is the process of exciting certain particles inside atoms. More specifically, MRIs excite protons in the body’s water content.

MRI technologies use a strong magnet to align the protons in the same direction. Next, radio waves knock the protons out of alignment; when the radio waves are turned off, the magnetic field realigns the protons. Depending on the type of tissue, the health of the tissue, and other factors, the protons realign at different speeds. Sensors on the MRI capture this activity and use the information to create images of the organs.

When did MRIs come out?

In 1969, Dr. Raymond Damadian's magnetic resonance could tell the difference between cancer cells and non-cancerous cells. He combined magnetic resonance with imaging to design and build the world’s first MRI in 1974; Damadian created the first MRI image in 1977. The new MRI machines are built on this first version.

When did MRI become available?

Damadian founded FONAR Corporation, which produced the first commercially available MRI machine in 1980. The earliest versions were very large and expensive, so it took some time for them to become widely available to patients.

Impact of High-Resolution Imaging

High-resolution imaging can help healthcare professionals see organs, blood vessels, and tissues more clearly. High-resolution MRI scans can help practitioners visualize very small structures, for example. The information they gain can help them make accurate diagnoses, create treatment plans, and assess the outcomes of treatment.

Key Technologies Enhancing MRI

Artificial Intelligence

Artificial intelligence (AI) uses computer algorithms to process information much faster and more accurately than humans can – and with substantially less raw data. Because less data is needed, patients spend less time in the MRI machine.

Larger Bores

The first MRIs had rather small bores, or openings through which patients would pass through during their test. Today’s MRIs can have larger bores – up to 80 centimeters. The larger bore is a game-changer for bariatric patients and those with claustrophobia; it also provides the imaging personnel better access.

In-System Entertainment

Undergoing a medical test is stressful for most patients, and the noise and close quarters of an MRI machine just add to the anxiety. In-system entertainment gives an anxious patient something else to think about. The in-bore system can immerse the patient in clear sound and music while still being able to voice commands from the technologist.

Benefits of New MRI Technologies

Improved Diagnostic Accuracy

Higher resolution and clarity can help doctors identify smaller anatomical structures and lesions that less powerful machines may miss.

Streamlined Workflow for Medical Practitioners

Workflow refers to the process of setting up the MRI, positioning patients, and acquiring the images. With our Swift MRI, medical practitioners can benefit from significantly faster scan times, optimizing workflow like never before. These new MRI machines not only speed up exams but also simplify the scanning process, enhance healthcare providers' decision-making, and improve overall patient comfort.

Enhanced Patient Accessibility

New MRI machines have a larger bore that can accommodate larger bodies, and make tests more comfortable for patients who experience claustrophobia or anxiety during testing.

Innovations in Patient Safety and Comfort

MRIs have always been generally considered a safe and comfortable approach to imaging, but the newest MRI machines are even safer and more comfortable. Larger bores and faster scan times make MRIs much easier for patients.

Safety Protocols in Modern MRI Practices

While they do not use radiation, MRIs do use powerful magnets that can turn metal objects into dangerous projectiles, which means monitoring equipment and other medical devices cannot be used near them.

Advances in technology have also made MRIs safer. New MRIs can use less powerful magnets without losing image quality.

Comfort Features for Patients During Scans

Today’s MRI machines offer comfort features, such as:

• Dimmable lights
• Sound
• Wide bores
• In-system entertainment
• Padding on the table

Advantages and Limitations of MRI

MRI provides several advantages, especially when it comes to detecting abnormalities in soft tissue. However, like all imaging techniques, it does have some limitations. Here’s a breakdown of what makes MRI so valuable in medical diagnostics:

Advantages:

• Detects abnormalities and diseases that might be missed by other imaging methods
• Provides superior soft tissue contrast, making it easier to differentiate between fat, water, muscle, and other tissues
• Does a better job of visualizing complex internal structures, like the brain, heart, and joints

Limitations:

• Longer exam times compared to other imaging methods
• Not as widely available, and often more expensive
• Noisier and more enclosed, which can cause discomfort for some patients

Common Uses of Advanced MRI Technology

Advancements in MRI technology have expanded its use across a variety of medical fields. Modern MRI machines, like the Swift MRI, an AI-powered MR image enhancement solution, allow for more efficient scanning and greater patient comfort, leading to more widespread applications, such as:

• Brain scans
• Enhanced imaging for patients with implants
• Bedside scanning with portable MRIs for critically ill patients

Applications in Clinical Diagnosis

MRI is an essential tool for diagnosing a wide range of conditions. Some of the key clinical applications include:

• Assessing injuries, such as torn ligaments or cartilage damage
• Imaging tumors and cysts for more accurate diagnosis
• Evaluating heart problems such as blockages or structural defects
• Breast cancer screening for high-risk patients
• Assessing liver diseases, pelvic pain, or other internal organ issues

Research Applications in Medical Studies

MRI technology has also made significant contributions to research. One of the most notable advancements is functional MRI (fMRI), which allows researchers to observe brain activity in real time. This helps in understanding how a normal, diseased, or injured brain functions. The latest MRI machines are also used to track the effectiveness of new treatments or medications, providing invaluable insights into patient outcomes.

Preparing for an MRI Scan

One of the best aspects of MRI scans is that they usually require minimal preparation. Patients are typically asked to remove any metal objects, such as jewelry or watches, to avoid interference with the magnetic field. Here's what else you should know:

• No need for fasting before the scan unless otherwise directed
• You can usually take your medications as prescribed
• Comfortable clothing is recommended, avoiding metal in garments such as underwire bras or zippers
• Be aware of the magnetic field, which remains active even when the MRI is not in use

What to Expect During the Procedure

An MRI machine is a large, tube-shaped magnet. When you lie on the movable table, it slides you into the tube. The technologist will be in another room, monitoring the scan, but you'll be able to communicate with them through an intercom if needed.

• The MRI machine produces tapping, thumping, and other noises, which are normal and come from the magnet moving. To make you more comfortable, you may be given earplugs or headphones.
• Sometimes, an MRI with contrast may be ordered to provide clearer images. If so, an IV will be placed in your arm to administer the contrast material.
• Stay as still as possible during the scan to ensure the clearest images.
