MR does not use ionizing radiation. Rather, it creates images of organs and tissues with powerful electromagnets, sophisticated computers, and radio-frequency waves. Years of experience have shown no known harmful effects from the magnetic fields and radio-frequency pulses used in this hospital. Because of this, MR is often the first choice for imaging babies and children. It is considered a "non-invasive" test because the machine takes pictures without touching the body.
Prior to entering the MR room, all individuals are checked for metallic items on or within the body. Certain items -- cardiac pacemakers, rectal implants and other ferromagnetic objects -- may not be safe for the MR scanner, so please check with us or your physician prior to coming to the hospital.
