MRI (Magnetic Resonance Imaging) is a non-invasive imaging test that uses a magnetic field and radio waves to create detailed images of organs, tissues, and bones inside the body.
Here’s how it works:
- Magnetic Field: You are placed inside a large, cylindrical magnet.
- Radio Waves: Radiofrequency pulses are sent into your body.
- Image Creation: The machine detects the signals from your body and uses them to create images on a computer screen.
MRI can be used for a variety of purposes, including:
- Brain and spinal cord: To diagnose conditions such as tumors, strokes, multiple sclerosis, and infections.
- Heart: To evaluate heart function and structure.
- Joints: To diagnose conditions such as arthritis, ligament tears, and cartilage damage.
- Abdomen: To examine organs such as the liver, pancreas, kidneys, and spleen.
- Blood vessels: To detect blockages or narrowing of arteries.
MRI is a safe procedure that does not involve radiation. However, it is not suitable for people with certain metal implants or pacemakers.
If you have any questions about MRI or whether it is right for you, please talk to your doctor.
