MRI is a test used to create pictures of the inside of the body. This is done with a special machine that uses a strong magnet. MRI scanners come in different sizes and shapes, including standard (A), wide-bore (B), and open (C).
For an MRI scan, you lie still inside the machine while it takes pictures. The technologist is not in the room with you, but they are nearby and can see you and talk to you.
