Quizplus · Accepted Answer

MRI technology uses powerful magnets to align the hydrogen atoms in the body's water molecules. When a radiofrequency pulse is directed at the aligned hydrogen atoms, they temporarily move out of position and release energy. This energy, captured by the MRI machine, creates detailed images of the body's internal tissues and organs.
