[0002] Nuclear magnetic resonance is a physical phenomenon that refers to the process in which the energy level of an atomic nucleus changes due to the resonance absorption of radio frequency (RF) radiation of a specific frequency in an external magnetic field. Nuclear magnetic resonance examination is an important medical diagnostic technology used to detect the internal structure and organs of the human body and help doctors diagnose various diseases.
