If you’ve ever had an injury, chances are you’ve had an imaging exam. These tests are powerful tools that help doctors diagnose a range of conditions. However, not all imaging tests work the same way. Understanding the difference between an X-ray and an MRI can help you have a more informed discussion with your doctor about your care.
When Doctors Use X-Rays
An X-ray uses invisible beams of radiation to produce 2D images called radiographs. Solid or dense tissues like bones and teeth absorb the most radiation, so they appear white. Soft tissues like organs, muscle, and fat don’t absorb radiation as easily, so they appear in shades of gray.
X-rays are commonly used for identifying bone problems, such as:
- Dislocations
- Fractures
- Misalignments
- Narrowed joint spaces
This makes X-rays useful for identifying major bone problems. However, they don’t capture subtle bone injuries, soft tissue injuries, or inflammation.
When an MRI Is Needed
Magnetic resonance imaging (MRI) uses large magnets and computer-generated radio waves to create detailed 3D images that can be viewed at different angles. MRI scans do not use radiation, but they produce clearer images than X-rays.
They are especially useful for spotting sports injuries and musculoskeletal conditions, such as:
- Cartilage loss
- Joint inflammation
- Nerve compression
- Spinal injuries
- Torn or detached ligaments, tendons, muscles, and cartilage
Can I Get an MRI?
In most cases, MRI scans are safe for people with metal implants. Yet, unless the device is certified as MRI safe, they might not be able to have an MRI. Non-compatible devices may include:
- Bone growth stimulators
- Cochlear implants
- Implanted drug infusion pumps
- Implanted pacemakers
- Intracranial aneurysm clips
- Neurostimulators
If your podiatrist recommends an MRI scan, they’ll ask detailed questions about your medical history and any medical devices or implants you may have in or on your body.
Move Past the Guesswork
Lingering foot and ankle pain is frustrating, even more so when the cause isn’t obvious. When something feels off, guessing isn’t enough. Get to the root of the issue with the experts at The Foot & Ankle Center.
Our knowledgeable podiatrists will determine if an MRI scan is right for you. To inspect bones, they also offer digital radiography, an advanced form of X-ray inspection that produces a digital radiographic image instantly on a computer.
They provide thorough evaluations, personalized treatment plans, and offer safe, effective treatment options that relieve pain quickly. Give us a call at (314) 487-9300 or fill out our online contact form to schedule an appointment today!
