MRI is also known as Magnetic Resonance Imaging (MRI), the full name of which is Magnetic Resonance Imaging (MRI). The nuclei that are often utilized by people are 1H, 11B, 13C, 17O, 19F, 31P. At the beginning of the birth of the technology was known as Nuclear Magnetic Resonance Imaging (NMRI), and in the early 1980's the term NMR Imaging (NMRI) became more and more familiar to the public as a new technology in the field of medicine. The term NMR imaging (NMRImaging) became increasingly familiar to the public. With the installation of large magnets, some people became concerned that the letter "N" might have a negative impact on the development of MRI.
Additionally, the word "nuclear" tends to give hospital staff an image of another nuclear medicine department in the M***Vibration Laboratory. Therefore, in order to emphasize the advantages of this technique, which does not produce ionizing radiation, and to differentiate it from nuclear medicine, which uses radioactive elements, radiologists and equipment manufacturers have agreed to shorten the term "magnetic resonance imaging" to "magnetic resonance imaging (MRI)".

Expanded Information:
Magnetic **** vibration in the checking process, the particles are ordered throughout the magnetic field. There are two general types, the lower energy levels are parallel and in the same direction as the larger magnetic field, and the higher energy levels are parallel and inverse to the larger magnetic field. When the magnetic field is restored, these particles return to their original state. Different tissues have inconsistent rates of particle recovery because of the different types. Because different tissues can be derived.
Doing nuclear magnetic **** vibration is to detect whether the body parts are not the appearance of mutations, so as to determine whether the emergence of tumors as well as dispersion and development of the direction and speed. This test can detect the symptoms of the disease early and make timely response to deal with the disease. It can also be used to monitor recovery during treatment. It is also a good test for women who are pregnant.
