Someone is worried that doing an MRI will hurt the body, in fact?

In fact, an MRI does not harm the body.

MRI is not radioactive, its imaging method is magnetic field imaging, there is no harm to the human body, and it is a very safe means of examination.

It is understood that NMR was discovered on the basis of the development of solid-state microscopic quantum theory and radio microwave electronics technology. The world's first medical MRI machine was invented by the German company Siemens.

Since the invention of the MRI machine, there have been no news reports that endanger human health, and there has been no genetic mutation caused by MRI examinations. However, there is a limit to any inspection and it should never be over-examined.

Precautions for MRI examination

1. When doing MRI examination, it is necessary to pay attention to the fact that there can be no metallic implants in the body, and if there is, it should be indicated to the examining doctor in advance, and the MRI examination can be stopped if it is not necessary.

2. Due to the relatively long time of MRI examination, which takes about 20-30 minutes, the patient should remain still during the examination and cannot move at will. Patients who cannot remain relatively resting for a long time due to special reasons should also be explained in advance.

MRI is not harmful to the body and is very safe, because MRI is only an imaging of a magnetic field, without any radioactive material. MRI has obvious advantages for screening early lesions, but no matter what kind of examination is done, there will be certain limits, and some people who are not suitable for MRI should not undergo excessive examination.

Doing an MRI will not harm the body, it is better than CT, mainly using MRI molding, and it will not cause harm to the body.

That bit of nuclear radiation is not a threat to the human body.

The first thing to see is whether the dress you are wearing is very **. If it's very**, generally boys like to look at ** women. And directly look at whether the clothes are more fashionable.

1. Doing an MRI is not harmful to the body.

An MRI does not require X-rays, it uses a magnetic field and an electronic computer to image the inside of the human body. MRI is not radioactive, so it is not harmful to the human body, and so far, there have been no cases of injury caused by MRI.

2 MRI does not affect heredity.

So far, it has not been found that the patient has no variation in the genetic material, i.e., chromosomal variation, genetic variation, etc., after the use of MRI, and the incidence has not increased. In animal studies, no adverse effects of strong magnetic fields on organisms have been found.

31.Be sure to remove all metal objects.

2.If you have an abdominal exam, you can keep your stomach fast for 4 to 6 hours before the exam.

3.Don't wear makeup. Cosmetics contain metals.

4.Adjust your mentality, don't be overly anxious, and face it normally.

41.Patients who have metal stents in their heart or other vital parts of the heart cannot have an MRI. Such as pacemakers, vascular bypasses, vascular stents, etc.

2.Patients with high fever.

3.Pregnant women try not to do it.

4.Patients fitted with insulin pumps do not do it.

5.Young children with severe depression, phobias, hyperactivity should not be.
