5 thoughts on “Does magnetic resonance have side effects?”

Have. 1. MRI is closed, the noise is large, and the light is darker. Patients with closed phobia should not be done for this examination; 2, metals have a greater impact on the MRI Magnetic items, heart pacemakers, or other human body implanted metal medicine equipment are harmful and cannot be checked. 3, MRI, the time required for the MRI to check for a long time, the patient needs to cooperate quietly, and it is difficult to cooperate with children. It is necessary to choose carefully. Pucting information: If Note: 1. There are other metal foreign objects that cannot be removed in the body, such as fixed objects in metal, artificial joints, metal dentures, brackets, silver clips, shoils and other metals In order to check the relatively taboos, the inspection must be observed closely to prevent the metal from moving in the strong magnetic field in the inspection to damage the neighboring large blood vessels and important tissues, and has serious consequences. 2, if there is no special need, do not receive nuclear magnetic resonance inspections. Metal dentures with metal contraceptive ring and activity must take it out before checking. 3. Before entering the MRI test room, remember to remove the mobile phone, magnetic card, watch, key, gold and silver jewelry, etc. with magnetic or metallic properties. Otherwise, it may affect the uniformity of the magnetic field during inspection, resulting in the interference of the image, which is not conducive to finding the lesion. 4. Due to the effect of a strong magnetic field, metal items may be sucked into the nuclear magnetic resonance machine, which will cause damage to the nuclear magnetic resonance machine, and it will also cause unnecessary losses of personal property.

If you really want to investigate: MRI is still dangerous to the human body.
In the principle of the principle: MRI, referred to as MRI, is a biomagnetic spinning imaging technology. Signals are generated, the detector is detected and the computer is entered, and the image is displayed on the screen after processing. In other words, MRI is different from CT, X -ray, and radiological imaging. It does not have radioactivity. It only rely on a certain strength magnetic field to stimulate the internal atom inside the object. This pulse signal generates the required image.
. If you have to deepen the damage it brings to the human body, it is mainly because the powerful magnetic field can cause metal displacement, such as the metal fragments in the eyes and brains. Under the action of the magnetic field He is blind, so people who have had a history of brain surgery and people who have been injured in the eyes, and welding workers must pay attention to the head X -rays in advance.
It strong magnetic fields can cause metal items such as fork, key, oxygen cylinder and other flying equipment centers, causing the patient's casualties. Therefore, any metal items are strictly prohibited in the house.
Is that the damage similar to radiation is not obvious. As long as you are not every day, you will not have any side effects, and there is no need to wear strict protective equipment.
does not need to be too nervous. As long as you pay attention to the above problems, MRI will not bring any side effects. Imagine the safest sponge. If you use improper use, there are hidden safety hazards. No absolute safety! Intersection Intersection
Magnetic resonance is a spin magnetic torque that flipped the hydrogen atom under a strong magnetic field. Because the parts of the human body belong to the water (the organic matter also contains hydrogen), it can be judged and changed according to the amount of water. This principle is a change below the atomic level, which is lower than the basic unit of human below. So it will not cause damage. But it is obvious that the human body is a complex system. The interaction of strong magnetic fields and biologics will definitely affect human nerve regulation and endocrine. Moreover, people are not accustomed to strange external environments with strong magnetic fields The magnetic field is 1000 times strong, and you can easily suck 10 kg of fire extinguisher). Therefore, it is recommended not to check frequently, and the inspection time should not be too long. But it is certain that the damage to the human body must not be strong in the human body.
Magnetic resonance imaging (MRI) is to reconstruct the imaging technology of the image by the signal generated by the collection of magnetic resonance. Therefore, it is also called a self -rotated image imaging and nuclear magnetic resonance CT. MRI can make CT's unable to show the development of the disease, which is another major development in the field of medical imaging. It is a new technology used in clinical image diagnosis in the early 1980s. Compared with CT, it has no radiation damage, boneless pseudo -shadow, multi -faceted, multi -parameter imaging, highly soft tissue distinguishing ability, and unique advantages such as vascular structure without using a contrast agent. It is almost suitable for different diseases of the systems of the whole body, such as tumors, inflammation, trauma, degenerative lesions, and various congenital diseases. The display of the brain, spinal and spinal disease is better than that of CT. It does not use vascular contrast agents, that is, the structure of the vascular structure, so it has its own uniqueness to the mutual identification between blood vessels, lumps, lymph nodes, and vascular structures. It also has the ability to distinguish the soft tissue several times higher than CT, and sensitively detects changes in water content in the tissue ingredients, so it is often more effective and earlier than CT. MRI can clearly and comprehensively show the heart cavity, myocardium, pericardium, and other small structures in the heart. It is a reliable method for diagnosing various heart diseases and cardiac functional tests. During the MRI examination, patients should be exempted from magnetic items such as iron, such as watches, metal necklaces, fake teeth, metal buttons, metal contraceptive rings, etc., so as not to affect the uniformity of the magnetic field, result in pseudo -shadows of the image, which is not good for lesion display display Essence Those with a heart paceer are strictly forbidden to perform Mili examination. Inside the body, there are sholes, silver clips, internal metal fixed boards, and fake joints, and must be carried out carefully. When checking, you must observe closely to prevent the metal from moving in the high magnetic field and damage to the neighboring large blood vessels and important tissues. For children or unclear children who are difficult to check, the sedative should be used appropriately. MRI examination should be empty for the upper abdomen (liver, pancreas, kidney, adrenal glands, etc.). Before checking, you can drink sufficient water to make the boundary between the stomach and liver and spleen show more clear. /xyy/homePage //

What is not harmful
The people who are falling are also harm
your knife hurts hands and hurts
Are you afraid?
don't have to be afraid
