Magnetic resonance imaging (MRI) is a diagnostic test that uses magnetic and radio waves to produce images of the structures in the body. It can be used to produce 3D images from different angles.
When it's done:
MRI is performed to diagnose brain and spinal cord abnormalities, breast diseases, heart and blood vessels disorders, bone and joint disorders and internal organs disorders.
MRI can help diagnose various conditions such as:
- Disorders of the eye and internal ear
- Multiple sclerosis
- Spinal cord injuries
- Ballooning of the blood vessels (aneurysms)
- Joint disorders such as arthritis and bone infections
- Breast cancer
When to Avoid:
Consult your doctor if you are pregnant, because the effect of magnetic waves on the baby is not well understood, or if you suffer from any kidney or liver diseases, as they may limit the use of injected contrast agents during the test.
Consult the doctor if you have any metal or electronic devices in your body that may interfere with the test such as:
- Artificial heart valves
- Cardiac pacemaker
- Any implants
- Metallic prosthesis
How to prepare:
You can eat and take your medications as per your regular schedule. You may be asked to wear a hospital gown and to remove any jewellery you are wearing. You may be required to remove any removable dentures, hearing aids, watches or eyeglasses before the test.
