Medical imaging plays a crucial role in diagnosing diseases and injuries. Among the most commonly used imaging techniques are X-ray and Magnetic Resonance Imaging (MRI). Although both help doctors see inside the body, they work very differently and are used for different purposes.

What Is an X-Ray?
What Is an X-Ray?
An X-ray is an imaging technique that uses low-dose ionizing radiation to create images of the body, especially bones. Dense structures like bones appear white, while softer tissues appear darker.

Common Uses of X-Ray
Common Uses of X-Ray
- Bone fractures
- Joint dislocations
- Chest infections (pneumonia, TB)
- Dental problems
- Arthritis changes
- Lung and heart size assessment
Advantages of X-Ray
Advantages of X-Ray
- Quick and painless
- Widely available
- Low cost
- Useful in emergencies
Limitations of X-Ray
Limitations of X-Ray
- Limited soft-tissue detail
- Uses radiation (though very low dose)
- Not ideal for muscles, ligaments, or brain
What Is MRI?
What Is MRI?
Magnetic Resonance Imaging (MRI) uses a strong magnetic field and radio waves to produce detailed images of soft tissues. MRI does not use radiation.
