Are there any side effects to MRI for children?

With the development of modern science and medical technology, there are more and more ways to detect physical health conditions, and magnetic resonance imaging is one of them. Magnetic resonance imaging is a method for detecting the presence or absence of lesions in muscles, nerves, soft tissues, brain, etc. But when many people hear about magnetic resonance imaging, the first thing that comes to their mind is radiation. Many people are afraid that it may be harmful. Will it have any impact or side effects on people?

1. What is Magnetic Resonance

Magnetic resonance imaging is an examination method that uses electronic computers to perform image analysis and diagnosis on human body cross-sections. It does not use X-rays but magnetic fields. Its basic principle is that the hydrogen atoms contained in the human body will resonate when given specific high waves under a strong magnetic field, generating a high-wavenumber electromagnetic wave. Nuclear magnetic resonance uses this property to collect, process and graph the changes in the magnetic field using electronic computers.

2. The role of magnetic resonance

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.

3. MRI examination is harmful to the human body

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.

IV. Precautions

The noise during magnetic resonance imaging is relatively loud, which may cause some damage to the patient's hearing. (However, patients do not need to worry too much, because when doing MRI, medical staff will ask patients to wear earplugs for protection to reduce the noise to as low as possible.)
