Theory and Function of NMR

The definition of NMR

NMR (nuclear magnetic resonance) means that the atomic nucleus, which has a distance, occurs the Zeeman splitting in an external magnetic field and absorbs the radiation frequency.

The application of NMR

As the development of technology, NMR has become a common imaging method for detecting diseases. It will not influence human health.

Detecting diseases

NMR is a new method for detecting diseases in medical science. It has the advanced function for detecting the diseases, such as, brain, thyroid, liver, gall bladder, spleen, kidney, pancreas, adrenal gland, uterus, ovary, prostate and other organs.
This technology can also be used to detect tumors. NMR with the method of Diagnostic Imaging can find out cancer, cerebral infarction, cerebral hemorrhage, brain abscess, cerebral cysticercosis disease and congenital vascular malformation. For breast cancer, it can diagnose it early and as for high blood pressure, high cholesterol, high blood sugar, it can detect them through brains and hearts.

Being harmless to human

As we mentioned above, this technology is harmless to human. Because the process of NMR is magnetic phenomena and there is no radiation in this process. It is harmless to human. It is reported that there are not any reports, which reveal the harmness of NMR and there are no patients, who had been influenced by the NMR.


Although the NMR has the advanced ability in detecting diseases, it has its own limitation. For example, some patients are not suitable to receive this detection. Who are they? Persones who have the pacemakers, metallic foreigns in vivo and metal prosthesis are not suitable for this detection method. What’s more, pregnant women should not be detected by this technology.

So there is a saying, we have to follow the detection of doctors. We cannot take granted that the expensive methods are much better than cheap ones. We should choose the most suitable methods for ourselves.

This is the main introduction to the NMR technology. The NMR service is also welcome by scientists. Because they think the NMR analysis is the efficient technology among the medical science.
