Is it harmful to the body to take an MRI for vibration

MRI is not harmful to the body.

1. Since NMR is magnetic field imaging, not X-ray, it is not radioactive, so it is harmless to the human body and is very safe. So far, there have been no reports of harm caused by the use of MRI machines in hospitals, and no increased incidence of genetic mutations or chromosomal aberrations has been found in patients.

2. Magnetic resonance imaging is an examination method that uses an electronic computer to analyze and diagnose the image of the human body, which does not use X-rays, but magnetic fields, and its basic principle is that the hydrogen atoms contained in the human body will resonate after giving a specific high wave under a strong magnetic field, producing a high wavenumber of electromagnetic waves. Nuclear magnetic resonance (NMR) takes advantage of this property by using an electronic computer to collect, process, and graphize changes in the magnetic field.

3. MRI can show fat, organs, muscles, fast-flowing blood, bones and air. The internal structure of the organ can also be clearly displayed. Doctors can well identify tumors, inflammation, necrotic lesions, abnormal material deposition, functional obstruction, blood circulation obstruction and other lesions in the patient's body.

It is of great help in the diagnosis of various diseases of the nervous system, chest, abdomen and limbs.

MRI is not harmful to people. Nuclear magnetic resonance (NMR) is to place the human body in a special magnetic field, use radio frequency pulses to excite the hydrogen nuclei in the human body, cause hydrogen nuclei resonance, and absorb energy, and then be recorded by a receiver in vitro, and the image is processed by an electronic computer. MRI does not require injection of contrast agent, has no ionizing radiation, and has no adverse effects on the body.

However, MRI is not available in patients with pacemakers or those with certain metal foreign bodies implanted in their bodies.

Many people may have heard of MRI, but they don't know what the use of MRI is, it is generally only used when doing examinations in the hospital, MRI is now a more important examination technology, many diseases can be examined with MRI, so is it harmful to the body to do MRI? What are the effects of MRI on the dead body?

1. Is it harmful to the body?

There is no harm to the body in doing an MRI.

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. Will it affect heredity?

MRI does not affect heredity.

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

3. Precautions for nuclear magnetic resonance

1.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.

4. Not suitable for people

1.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.

5. It should not be done in the first trimester

In the first trimester of pregnancy, the embryo is in the stage of cell differentiation and development, which is susceptible to damage by various external physical factors, and the biological effects of MRI such as magnetic field, radiofrequency pulse, noise and thermal effect may cause hearing damage and malformation of the fetus, so it is generally not recommended to do MRI examination for fetuses within 3 months of pregnancy. The best time for an MRI is between 4 and 9 months of pregnancy.

Recently, a man in Zhoukou, Henan Province went to the hospital for an MRI examination, and after the examination, he was forgotten by the staff at that time in the examination cabin. The man claimed that he had been shouting in the inspection cabin but no one answered, and that it was about 20 minutes before he slowly climbed out of the cabin because he really had no choice. What made the man feel extremely angry was that when he came out, he found that the medical staff at the time were playing with his mobile phone next to him, so he found the reporter to explain the incident, and the man and the reporter found the hospital together.

At that time, the director of the MRI department apologized to the man, and claimed that all the interns present at the time were derelict in their work, and later the hospital also stated to the man that all the interns had been dismissed, and the relevant departments were deducted 2,000 yuan, and the doctor on duty at that time was also given a warning and punishment. <>

Many netizens expressed great interest in whether long-term contact with the body of an MRI would be harmful to the body. According to doctors, MRI is a common imaging test that does not have any impact on human health. However, since the metal object will interfere with the MRI machine, it is necessary to remove all metal objects from the body before the MRI is performed to prevent the final result of the MRI.

For this matter, I just want to say that the hospital involved is quite irresponsible, and we often see that when some institutions that have had accidents do not want to take responsibility, they will say that the person in charge of the accident at that time are all temporary workers, and the interns shirk their responsibilities, and claim that they have nothing to do with the agency, but we all know that after all, these so-called temporary workers and interns also work for these institutions, although it is their own work deviations and mistakes, But don't these institutions have oversight and management responsibilities? Obviously, there is, so the hospital in this case is seriously suspected of shirking responsibility and does not want to take relevant responsibility for the man, although it does not have any impact on the body in the examination cabin of the MRI room, but after all, it is a medical accident of the doctor, so the man should report to the police in time to complain about this hospital and ask this hospital for relevant compensation, and this hospital must not be fooled around. It also makes this hospital remember for a long time to prevent this kind of thing from happening again.
