Quizplus · Accepted Answer

A CT scan (computed tomography) uses x-ray technology to take multiple images of the body from different angles, which are then combined by a computer program to create a detailed picture of the inside of the body. This process is similar to the description given in the question. PET scans use radioactive tracers to measure metabolic activity in the body, MRI scans use magnetic fields and radio waves to create images, and fMRI scans measure changes in blood flow to study brain function. None of these other options match the description given in the question.
