A medical technique that uses a strong magnetic field and radio frequency electromagnetic waves to investigate the human body. Hydrogen atoms in disease cells differ from normal body cells. Since bodies are mostly water, protons in hydrogen atoms are used in the process. The valence electron is induced to lose energy and the protons with their north and south magnetic poles, align themselves along the magnetic field.
