Is enhanced magnetic resonance imaging harmful to humans?

With the gradual progress of modern medicine, nuclear magnetic resonance imaging has appeared in people's lives. However, the emergence of this medical device has brought a lot of convenience to people on the one hand, but it has also brought adverse effects on people on the other hand. Nuclear magnetic resonance imaging is chosen to treat diseases in medicine, but if the magnetic resonance imaging is strengthened, it will cause certain harm to the human body, because magnetic resonance imaging is emitted by laser rays, which will cause certain damage to human cells.

At present, the magnetic field strength of medical magnetic resonance imaging is generally between 0.2 and 3.0 T (T is the unit of magnetic field strength, 1 Tesla = 10,000 Gauss, and the magnetic field strength in nature is 0.5 Gauss). According to the latest research data in the world, there is no definite evidence that MRI examinations are harmful to the human body. However, for certain groups of people, such as women in early pregnancy, MRI examinations should be performed with caution, although there is no evidence that MRI examinations have adverse effects on fetal development. Any radiological examination such as X-ray fluoroscopy, photography, and CT will produce harmful radiation to the human body. Currently, the medical community recognizes that X-rays are carcinogenic, and there is a widespread dangerous situation of abuse of X-ray examinations in China. Therefore, when a medical examination is required for the diagnosis of a disease, it is necessary to weigh the pros and cons and try to choose safe, harmless, and non-invasive examinations to minimize iatrogenic damage.

There are three types of magnetic resonance imaging: strong magnetic field, radio frequency field and gradient magnetic field. According to international standards, the magnetic field less than 3T on the market is generally considered to be harmless to humans, which is different from radiation products: CT, X-ray machines, molybdenum target mammography machines, etc.

Since MRI is magnetic field imaging rather than X-ray and is not radioactive, it is harmless to the human body and is very safe. So far, there has been no report in the world of any harm caused by the use of MRI machines in hospitals, nor has any increase in the incidence of gene mutations or chromosomal aberrations in patients been found.

MRI can show fat, internal organs, muscles, fast-flowing blood, bones, and air, etc. The internal structure of the organs can also be clearly displayed. Doctors can easily identify tumors, inflammation, necrotic lesions, abnormal substance deposits, functional obstructions, blood circulation obstructions and other lesions in the patient's body. It provides great help in the diagnosis of various diseases of the nervous system, chest, abdomen and limbs.
