Magnetic resonance imaging (MRI) is a powerful diagnostic imaging tool that provides detailed, cross-sectional images of your organs, bones, soft tissues, and even brain activity. Unlike CT scans or X-rays, MRI scans do not require radiation. This makes them a safe and preferred option for many diagnostic procedures.
At Apex Orthopaedics Spine & Neurology in Charlotte, we offer state-of-the-art MRI technology to help physicians gain a clearer picture of your internal structures and diagnose a wide range of medical conditions.

What is Magnetic Resonance Imaging (MRI)?
Magnetic resonance imaging (MRI) is a body imaging method that utilizes powerful radio waves and magnetic fields to produce precise cross-sectional images of the human body. These images provide valuable insights into the structure and function of various organs, tissues, and bones.
Unlike X-rays, which primarily image bones, MRI scans excel at visualizing soft tissues like muscles, ligaments, tendons, and the brain. Here’s how an MRI scan works.
Magnetic Field
During an MRI scan, you’ll lie inside a large, cylindrical machine that generates a strong magnetic field. This magnetic field aligns the protons (tiny particles) within your body’s atoms.
Radio Waves
Radio waves are then pulsed into your body at specific frequencies. These radio waves cause the aligned protons to absorb energy.
Signal Detection
Once the radio waves are turned off, the protons release the absorbed energy. This energy release is detected by the MRI machine and converted into detailed images.
What Is an MRI Scan Used to Diagnose?
The detailed images generated by an MRI scan allow physicians to diagnose a wide range of medical conditions, including the following.
Musculoskeletal Conditions
MRI scans can reveal abnormalities in muscles, ligaments, tendons, bones, and joints, aiding in the diagnosis of sports injuries, arthritis, bone fractures, and spinal cord problems.
Neurological Conditions
MRI scans are invaluable for diagnosing brain tumors, multiple sclerosis, stroke, and other neurological conditions by providing detailed images of the brain and spinal cord. They can also be used to assess nerve damage or inflammation.
Cardiovascular Conditions
While not as common as other imaging techniques for the heart, MRI scans can be used to assess the heart and surrounding blood vessels, helping diagnose abnormalities like heart defects or aneurysms.
Cancer Diagnosis and Staging
MRI scans can be used to detect tumors in various parts of the body and determine their stage (extent of spread). MRI scans are particularly useful for imaging tumors in soft tissues where other imaging modalities may have limitations.
Other Conditions
MRI scans can also be used to diagnose other conditions such as internal bleeding, birth defects, and abnormalities of the abdomen or pelvis.
What Should I Expect When Getting an MRI?
An MRI scan is a relatively painless procedure. Here’s a general overview of what to expect.
Consultation
Before scheduling an MRI scan, your doctor will discuss the procedure with you, answer any questions you may have, and determine if an MRI is the right diagnostic tool for your condition. They will also explain the potential risks and benefits of the scan.
Screening Questionnaire
You will be asked to complete a screening questionnaire to identify any potential contraindications for MRI, such as claustrophobia, certain medical implants, or pregnancy. Metal implants or certain types of claustrophobia may make you ineligible for an MRI scan. If you have any concerns, discuss them with your doctor beforehand.
The Day of the Scan
On the actual day of your scan, you will need to change into a gown and get rid of any metal objects or jewelry that could interfere with the magnetic field. This may include watches, rings, dentures, or piercings. Lockers are usually provided to store your belongings safely.
Positioning
A technician will help you position yourself comfortably on a movable table that slides into the MRI scanner. Depending on the area being scanned, you may need to lie flat on your back or stomach or in a specific position with coils placed around the area of interest. These coils help transmit and receive radio signals for image generation.
The Scan
The MRI machine will generate loud tapping or humming noises during the scan. Ear plugs or headphones may be provided to reduce these noises. The scan itself is painless and typically takes 30 to 60 minutes, although some scans may take longer depending on the complexity of the study. During the scan, it’s important to remain still as much as possible to ensure clear image quality.
After the Scan
Following the scan, the technologist will review the images and ensure they are of sufficient quality for diagnosis. The images will then be interpreted by a radiologist, a physician specializing in analyzing medical images. Your doctor will receive the report from the radiologist and discuss the results with you, explaining any findings and their implications.
Preparation for MRI
Here are some tips to prepare for your MRI scan.
- Inform Your Doctor: Tell your doctor about any medical conditions you have, medications you take, and allergies you may have. This will help them determine if MRI is the right imaging test for you.
- Metal Objects: Leave all jewelry, watches, credit cards, and other metal objects at home or in the locker provided. Metal objects can become projectiles in the MRI’s strong magnetic field.
- Clothing: Wear loose-fitting, comfortable clothing without metal fasteners or zippers.
- Claustrophobia: If you experience claustrophobia, let your doctor know in advance. Certain techniques like relaxation exercises or open MRI scanners may be available to ease your anxiety.
- Fasting: Depending on the type of MRI scan you are undergoing, you may be asked to fast for a few hours beforehand. Your doctor will provide specific instructions.
- Medications: Continue taking your prescribed medications unless your doctor instructs you otherwise.
- Ask questions: Don’t hesitate to ask your doctor or the technologist any questions you may have about the MRI procedure.
