Question

Quizplus · Accepted Answer

PET scans use radioactive glucose to produce images of brain functions by measuring the activity of cells in different parts of the brain. CT scans use X-rays to produce cross-sectional images of the body, while SQUIDs are used to measure very small magnetic fields and MRI uses magnetic fields and radio waves to produce detailed images of organs and tissues.
