Magnetic resonance imaging (MRI) exams use a strong magnet to take pictures of internal organs and tissues. MRI is different from CT or X-ray because it does not use ionizing radiation (X-rays). Images of the body are made by using magnets and radio waves, and the level of detail that an MR image can provide is exceptional. This is why MRI is usually the preferred method for the diagnosis of many types of conditions and injuries. There are no known biological risks for humans from being exposed to magnetic fields of the strength used in medical imaging. Therefore, MRI exams do not pose any risk to an average patient – just as long as appropriate safety guidelines are followed.
MRI is an extremely safe procedure when performed by trained experts. As such, the team at UCSF Health’s radiology department put together a few safety videos to remind patients and staff about the…
