MRI is painless. There is no radiation and there are no harmful side effect.

Magnetic resonance imaging (MRI) is a special radiological test that gives very clear, detailed pictures of organs and structures in the body. The test uses a powerful magnetic field, radio waves and a computer to create images in cross-section. Images are taken in a number of different levels or planes, which is one of the reasons why this test is so useful. While an x-ray is very good at showing bones, an MRI is especially useful at showing structures made of soft tissue (non-bony tissue) such as ligaments and cartilage and organs such as the eyes, brain and heart.
