Which of the following imaging techniques can be thought of as a three-dimensional X-ray?
A)MRI (magnetic resonance imaging)
B)CT (computerized tomography)
C)fMRI (functional magnetic resonance imaging)
D)PET (positron emission tomography)

Question

Quizplus · Accepted Answer

CT (computerized tomography) uses X-rays and computer algorithms to produce a three-dimensional image of the inside of the body. It can be thought of as a three-dimensional X-ray. MRI (magnetic resonance imaging) and fMRI (functional magnetic resonance imaging) use magnetic fields and radio waves to produce images of the body, while PET (positron emission tomography) uses radioactive tracers to produce images of metabolic activity. These techniques provide different information than a traditional X-ray.
