MRI vs. X-Ray: What’s the Difference and Which Do You Need?

If your doctor has recommended imaging, you may be wondering whether you need an MRI or an X-ray. While both tests help physicians see inside the body, they serve different purposes and provide different types of information.

At Independent Physicians Medical Center (IPMC) in Northeast Philadelphia, we offer advanced outpatient imaging—including digital X-rays and MRI services—to help diagnose injuries and medical conditions quickly and accurately.


What Is an X-Ray?

An X-ray uses a small amount of radiation to create images of dense structures inside the body, especially bones. X-rays are commonly used to:

  • Detect bone fractures
  • Evaluate arthritis
  • Identify joint dislocations
  • Examine chest conditions like pneumonia
  • Assess certain abdominal concerns

X-rays are fast—often completed in just a few minutes—and are typically the first imaging test ordered for injuries or bone-related issues.


What Is an MRI?

An MRI (Magnetic Resonance Imaging) uses strong magnets and radio waves to create detailed images of soft tissues, organs, and structures inside the body. Unlike X-rays, MRIs do not use radiation. MRIs are often used to evaluate:

  • Ligament and tendon injuries
  • Spinal conditions
  • Brain and neurological issues
  • Soft tissue injuries
  • Joint cartilage damage

MRI scans provide more detailed images than X-rays but typically take longer to complete.


Key Differences Between MRI and X-Ray 

FeatureX-RayMRI
Uses radiationYes (low dose)No
Best forBones, fracturesSoft tissues, ligaments, organs
SpeedVery fastLonger exam time
Detail levelBasic structural imagesHighly detailed images

Your doctor will choose the imaging test based on your symptoms and what needs to be evaluated.


When Might You Need an X-Ray First?

In many cases, especially after a fall or injury, doctors start with an X-ray to rule out fractures. If symptoms persist and soft tissue damage is suspected, an MRI may be ordered afterward.

For example:

  • Persistent knee pain after a normal X-ray → MRI may detect ligament tears.
  • Chronic back pain → MRI may reveal disc problems not visible on X-ray.

Having access to comprehensive imaging helps ensure accurate diagnosis.


Which Test Is Right for You?

The decision depends on:

  • Your symptoms
  • Your medical history
  • The area of the body being examined
  • Whether bone or soft tissue injury is suspected

If you’re unsure, your referring physician will determine the most appropriate study for your condition.
