Principles of nuclear magnetic resonance and its applications in medication

Abstract

There is no doubt that the Nuclear Magnetic Resonance is one of the most fascinating inventions in modern era. Nuclear magnetic resonance is the physical process of nucleus in the body, which align with the direction of magnetic field under the action of external magnetic field, resonant absorb the radio frequency pulse of a certain frequency. NMR spectroscopy is a branch of spectroscopy in which the resonant frequency is in the RF band and the corresponding transition is a transition of the nuclear spin on the magnitude of the nuclear energy. With its large-scale application in various aspects, people’s life was facilitated greatly. In the field of medication, as a new imaging technique, it has no negative effect on human health, and high-resolution image could be produced without any radiation. Millions of patients and injuries could get the correct diagnosis and lead a healthy life later on thanks to it.
