Is MRI harmful to children?

Magnetic resonance imaging is a relatively common examination method. It mainly uses protons in the magnetic field to form images. This type of MRI has no ionizing radiation and is a relatively safe examination method. So don’t worry too much when doing the examination. The same is true for children. It will not cause adverse harm. Of course, you should be aware of some precautions when doing this examination.

Magnetic resonance imaging uses the principle of protons in a magnetic field to form an image. It does not produce ionizing radiation and is a relatively safe method of examination. I suggest you do not worry about it. This method of examination does not cause radiation.

Nuclear Magnetic Resonance

Nuclear magnetic resonance is a physical process in which an atomic nucleus with a non-zero magnetic moment undergoes Zeeman splitting of its spin energy levels under the action of an external magnetic field and resonates to absorb radio frequency radiation of a certain frequency. Nuclear magnetic resonance spectroscopy is a branch of spectroscopy. Its resonance frequency is in the radio frequency band, and the corresponding transition is the transition of nuclear spin on the nuclear Zeeman energy level.

Application of MRI: Magnetic resonance imaging (MRI) has become a common imaging examination method. As a new imaging examination technology, MRI will not affect human health. However, six groups of people are not suitable for MRI examination, namely: people with pacemakers, people with or suspected metal foreign bodies in the eyes, people who have undergone aneurysm silver clip ligation, people with metal foreign bodies or metal prostheses in the body, critically ill patients with life-threatening conditions, claustrophobia patients, etc. Monitoring equipment, rescue equipment, etc. are not allowed to be brought into the MRI examination room. In addition, pregnant women who are less than 3 months pregnant should not undergo MRI examinations.

Magnetic resonance imaging, commonly known as MRI, is increasingly used in clinical practice because it does not cause any radioactive damage to the human body, can perform multi-directional and multi-level imaging, and can display the human body's anatomical structure and lesions in two-dimensional and three-dimensional ways. However, before undergoing an MRI examination, you must understand several examination precautions to avoid adverse effects.

1. Patients with pacemakers, heart stents, vascular stents, heart bypass grafts, or neurostimulators cannot undergo MRI.

2. Those with silver clips in the skull or metal foreign bodies in the eyeballs are prohibited from undergoing this examination.

3. People who have undergone arterial disease surgery (post-aneurysm surgery), heart surgery, and have artificial heart valves cannot undergo MRI.

5. If there are metal objects in the examination area (steel plates, steel nails, iron nails inside the body or skull), you should proactively inform the examining doctor of the situation in advance.

6. Women should take off bras with metal bra hooks, and pregnant women should be cautious when undergoing MRI.

7. Before the inspection, please remove any metal objects such as coins, glasses, pens and various magnetic cards to avoid affecting the inspection.
