Why are contrast agents used in MRI?

MRI scanning (magnetic resonance imaging) is a very safe and gentle method. Unlike regular X-rays or computed tomography (CT), no X-rays are used. Instead, images are created using powerful magnetic fields and radio waves, which makes MRI completely radiation-free.

MRI is used daily in healthcare and has no known long-term side effects in healthy people. The examination is therefore safe to perform even on repeated occasions or for sensitive groups, such as children or pregnant women after week 12 - if there is a medical indication.

There are certain restrictions on metal in the body, such as pacemakers, implants or old surgical clips, because the magnetic field can affect these. Therefore, all patients must fill out a safety form before the examination. MRI is also safe for the vast majority of people with claustrophobia, but you can be sedated before the examination if necessary.
