### In the lessons

In health and science lessons MRI is compared with X-rays: it uses no harmful radiation and shows soft parts like the brain, muscles and ligaments clearly. Patients lie still inside a noisy tube. Metal must be removed because of the powerful magnet. Phrases: «an MRI scan», «have an MRI», «MRI machine».
