Question

Quizplus · Accepted Answer

MRI scans use powerful magnetic fields to produce detailed images of internal body structures. The magnet creates a strong magnetic field that aligns the protons in the body's tissues. A radiofrequency pulse is then applied to the area being imaged, causing the protons to absorb the energy and spin in a different direction. When the pulse is turned off, the protons give off energy that is detected by a scanner and used to create an image. There are no radioactive chemicals or electrical activity involved in this process. EEG measures electrical activity in the brain, while radioactive chemicals could be used in PET or SPECT scans.
