Is MRI safe?

MRI is a commonly used imaging method that allows our doctors to see and better understand what is going on inside your body. Compared with other imaging methods such as x-ray, CT, and nuclear medicine,, MRI does not use high-energy radiation to create an image, and therefore it does not carry the very small risk of future cancer that is sometimes associated with x-rays and gamma rays. However, MRI has some unique safety considerations because of the strong magnetic fields and radio waves that are used. The magnetic field can attract some metals; therefore, let your doctor or the MRI technologist know if you have any metal on or inside your body. Use only the facility's provided clothing during the exam. MRI exams can be noisy, so you may be offered hearing protection. Some MRI scanner designs (the "narrow bore" type) can provoke feelings of claustrophobia in some patients. Contrast dyes are sometimes used, which may cause an allergic reaction in some patients.
