3. What does a CT scanner look like?

A CT scanner looks something like a donut. It encircles the relevant part of the patient's body completely, which allows it to take multiple images from a variety of angles, creating the detailed images for which the tool is popular. Unlike an MRI scanner, the patient will not be put into a 'tunnel' to have their scan. Therefore, CT scans are less likely to trigger a claustrophobic reaction than some other methods of scanning.
