Exploring the Science: How Does Magnetic Resonance Imaging (MRI) Work?

Are you considering a career as an MRI technician? If you are interested in helping others and want to learn more about science and technology, then becoming an MRI technician may be the right career path for you.
This article will explore what an MRI is and how it works. And, this information will help you decide whether you are ready to complete our AA Degree in MRI Technology program and prepare for the American Registry of Radiologic Technologists (ARRT) MRI Primary Pathway certification exam.

What is an MRI?

MRI stands for Magnetic Resonance Imaging, a noninvasive diagnostic test that helps doctors diagnose and treat medical conditions by creating detailed images of the body’s internal structures. Unlike X-rays or CT scans, which use radiation, MRI uses magnetic fields and radio waves, reducing the risk of health problems from radiation exposure.

What Can an MRI Help Diagnosis?

An MRI can help a doctor diagnose many diseases and disorders. Typical uses of an MRI include:

Neurology: Identifying brain tumors, strokes, multiple sclerosis, and other neurological conditions.

Orthopedics: Assessing joint damage, ligament tears, and bone infections.

Cardiology: Imaging the heart and blood vessels to detect abnormalities.

Oncology: Detecting and staging cancers in various parts of the body.

Abdominal and Pelvic Imaging: Diagnosing issues in the liver, kidneys, uterus, and other organs.

How Does Magnetic Resonance Imaging Work?

MRI is a complex topic, but attending the MRI Technologist degree program at CBD College will make it much easier to master using an MRI. Our instructors guide you through the curriculum and support you during lab work and training. In the meantime, here is a basic explanation of how a magnetic resonance imaging machine works:

Magnetic Fields

An MRI relies on magnets to align the hydrogen protons in your body’s water molecules. Hydrogen protons naturally spin in random directions, but when exposed to a strong magnetic field, they align, allowing the MRI to take images using radio waves.

Radio Waves

Once aligned, the radiofrequency pulses bounce off the protons, creating images of structures within the body. These pulses momentarily knock the protons out of alignment, and as they return to their original position, the protons emit energy signals.

Signal Detection and Image Formation

The MRI machine captures these signals. While medical software then processes the signals to create detailed images of internal body structures. Different tissues in the body emit signals at varying rates, which is why MRI can distinguish between soft tissues like muscles, fat, and organs.

What are the Key Components of an MRI Machine?

Here are the critical components of an MRI machine:

Magnet: MRI machines use a superconducting magnet that creates a strong, uniform magnetic field.

Gradient Coils: These allow the MRI machine to focus on specific areas of the body, creating images for the doctor to review and make better diagnoses and treatment decisions.

Radiofrequency Coils: These transmit and receive the radio waves that align the protons and create detailed images of internal body structures.

Computer System: Advanced software that converts raw signals into high-resolution images

Why Become an MRI Technician?

Becoming an MRI technician is more than just operating a machine; it’s about making a difference in people’s lives. Here’s why this career path is so rewarding:

MRI Technicians are in Demand

Advancements in medical technology and a longer life expectancy has increased the need for MRI technicians. According to the U.S. Bureau of Labor Statistics, the demand for MRI technicians is expected to grow 6 percent through 2033. That means more MRI technicians are needed and CBD College is ready to help you prepare for this rewarding career.

Opportunities for Professional Growth

As an MRI technician, you can specialize in advanced imaging techniques, work in healthcare settings you are passionate about, or even transition into research, teaching, or healthcare management roles. The sky’s the limit!

Personal Fulfillment

Every scan you perform contributes to a patient’s health. Whether you’re helping diagnose a severe condition or providing reassurance that everything is ok, your work directly impacts your patient’s health and well-being.
