Unlocking the Power of MRI: Comprehensive Guide to Uses, Benefits, and Risks

A revolutionary medical technology, MRI has transformed the way doctors understand and diagnose health conditions. Continue reading to learn more about scans, uses, and the benefits of using MRI.

What is an MRI?

According to an article by Ewald Moser and his colleagues,

“Magnetic resonance (MR) methods are non-invasive techniques to provide detailed, multi-parametric information on human anatomy, function and metabolism.”

MRI is vastly different from X-rays or CT scans. This is because MRI uses radio waves and magnetic fields to create detailed images of the body.

The Science Behind MRI Scan

Based on the nuclear magnetic resonance (NMR) principles, MRI’s magnets force the protons in the body to align with the magnetic field. Then, a radiofrequency current is sent through the body. The protons spin out of equilibrium and re-align with the magnetic field once the radiofrequency is turned off.

The spinning off and realignment of the protons give physicians enough data to differentiate between various types of tissues.

Benefits of MRI

Magnetic Resonance Imaging provides high-resolution imaging of the human body and helps detect various medical ailments. MRI can help detect:

• Neurological Conditions, including brain tumors
• Neurodegenerative Conditions
• Orthopedic Ailments

In addition to this, MRI gives way to functional imaging (fMRI), which allows doctors to comprehend brain activity, helping neuroscience research. The exceptionally detailed imaging allows accurate diagnoses and treatment, which ultimately boosts patient care and reduces the need for exploratory surgeries.

MRI Uses

MRI is now an indispensable tool, widely used in the areas discussed below.

Abdominal Imaging

As it is non-invasive, MRI is an excellent way to examine organs in the abdomen. Today, it is used to assess the liver, kidneys, and pancreas, aiding in detecting tumors, cysts, and abnormalities.

Neuroimaging

Magnetic Resonance Imaging helps examine the brain and spinal cord. The imaging helps doctors detect the presence of tumors, the possibility of strokes, and neurodegenerative diseases.

Cardiovascular MRI

Cardiologists also use MRI to assess the functionality of the heart. The imaging is used for critical information to diagnose heart diseases.

Musculoskeletal Imaging

To assess bone and joint health, orthopedic specialists use MRI as it aids in detecting ligament injuries, fractures, and arthritis.

Why opt for an MRI?

There are several advantages of using Magnetic Resonance Imaging. Some of these MRI benefits are listed down below.

High-Resolution Imaging

As discussed above, MRI provides detailed, high-resolution images that aid in diagnoses and treatment planning.Versatility
MRI is used for the entire body. This means from the brain and spinal cord to the abdomen and bones; MRI can be used to diagnose and treat the entire body.

Non-Invasive

As no ionizing radiation is produced by MRI, it is safer to use than X-rays and CT scans. In a comparison of MRI vs CT scans, MRI usually wins because it is safer.

Functional Imaging

fMRI assesses brain activity. Now, MRI can also be used to conduct in-depth research into the functioning of the human brain.

Improved Patient Care

MRI has significantly boosted patient care. This is because physicians are now more confident in their medical decisions. Backed by MRI scans, doctors now implement improved treatment plans, resulting in better outcomes.

Risks Associated With MRI

Although MRI is safer than CT scans and X-rays, it does pose a few risks nonetheless. MRI works using a magnetic field. This field can be harmful when it exerts force on objects of iron, especially those within the human body.
Individuals part of the following categories should avoid getting an MRI scan:

• Patients with implants, especially those with iron, should not get an MRI scan. This includes having pacemakers, implantable cardioverter-defibrillators, insulin pumps, stimulators, and cochlear implants
• People who have sensitive hearing, or get triggered by loud sounds, should avoid getting an MRI because the noise levels can reach up to 120 decibels
• Individuals diagnosed with renal failure need to consult their doctor before they opt for an MRI scan
• Pregnant individuals should avoid getting an MRI, although the negative correlation between fetal growth and MRI waves has not been established. However, in earlier months of pregnancy, contrasting agents might make their way into the fetus’ bloodstream
• Claustrophobic individuals might want to avoid getting an MRI scan, because the machine may induce intense anxiety or panic

Final Thoughts

Magnetic Resonance Imaging (MRI) has become one of the most used tools in medicine, and for good reason. The machine has the capability of detecting abnormalities throughout the body. As the technology continues to advance, it can produce even more accurate results making it essential for quality patient care.
