Perky is getting a CT scan. Some people think that this machine looks like a giant donut. What do you think? This bed moves back and forth. As Perky moves into the giant doughnut, the machine takes pictures of her insides. There are no "ouches" but the machine can be very noisy. Perky thinks getting an MRI scan is almost the same as getting a CT scan. Do you see any of Perky's friends in the big doughnut?
