Question

Quizplus · Accepted Answer

Modern computerized tomography (CT) images can be used to construct 3-D images, which was not possible in earlier versions. CT scans still use X-rays and may have a slight risk associated with radiation exposure, but advancements have made them safer for participants. CT scans can provide anatomical information but cannot measure activity in a structure, as functional imaging techniques such as fMRI and PET are used for this purpose.
