B)gamma rays
C)spinning protons
D)electrical currents

Quizplus · Accepted Answer

MRI uses a strong magnetic field to align the protons in water molecules in the body. Radio waves are then used to disrupt this alignment and the energy released as the protons realign is measured to create the images. X-rays and gamma rays are not used in MRI, and while electrical currents may be used in medical procedures, they are not the basis for producing MRI images.
