Multiple choice

What is the principle behind the operation of an MRI scanner?

  1. The interaction of magnetic fields with atomic nuclei

  2. The interaction of X-rays with atoms

  3. The interaction of ultrasound waves with tissues

  4. The interaction of radio waves with tissues
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

MRI scanners work by using strong magnetic fields to align the atomic nuclei in the body. Radio waves are then used to excite the nuclei, which causes them to emit signals that can be detected by the scanner. These signals are used to create images of the inside of the body.
