Use 1 to 5 to number the steps to show how an MRI machine scans and creates a detailed image of the inside of the body.
□ When the radio waves are turned off, the hydrogen atoms return to their original alignment, releasing energy.
□ The strong magnetic field aligns the hydrogen atoms in the body.
□ The MRI machine sends radio waves into the body, and the hydrogen atoms absorb them.
□ The MRI machine detects the released energy and uses it to create a detailed image of the inside of the body.
□ The patient lies down on a bed and is placed into the centre of a large circular magnet.
