Quizplus · Accepted Answer

In MRI technology, the area of the body to be imaged is exposed to radio frequency (RF) pulses. These pulses cause the protons in the body's tissues to align themselves in a particular way, which produces a radio signal that can be used to create an image. MRI does not use X-rays or radioactivity like other imaging technologies such as CT scans or PET scans. It also does not use gamma cameras which are used in nuclear medicine imaging.
