An MRI is a test that uses a magnetic field and pulses of radio wave energy to make pictures of your spine. MRI stands for "magnetic resonance imaging."
For this test, your body is placed inside a special machine that contains a strong magnet.
In some cases, a contrast material is used during the MRI scan. This means that you have a chemical injected into your bloodstream, through a vein (IV). The chemical makes certain areas show up better on the MRI pictures.
Thinking about the facts and your feelings can help you make a decision that is right for you. Be sure you understand the benefits and risks of your options, and think about what else you need to do before you make the decision.
