Magnetic resonance imaging (MRI) is a test that uses a powerful magnetic field, radio waves, and a computer to make clear and detailed pictures of organs and structures inside the body. MRI doesn’t use ionizing radiation like x-rays or CT scans.

During the test, you’ll lie on a table that’s attached to a large donut-shaped machine, called an MRI scanner. You may get contrast dye injected into a vein or in a drink that you swallow. This helps to show parts of your body more clearly.

MRI helps find tumours and diagnose diseases of the liver, heart, and intestines.
