Today (November 8th) is the world’s radiology day. Magnetic resonance is the “noble” in the image inspection, and the high impact makes it “tall”. Because I don’t know it, some people are almost injured. Not long ago, 32-year-old Shasha (pseudonym) went to the hospital to do magnetic resonance examination, at the time, the belly had a total of 4 warm babies, but fortunately, the radiological doctor found in time, it is impossible to be “strongly kiss” by magnetic resonance machine !
In fact, everyone has a lot of misunderstanding of magnetic resonance, and there are more questions, let the national clinical key specialist, Southeast University Affiliated Chinese Medical Hospital Radiologists are magnetic resonance “chaos anyway”, take you to understand the true magnetic resonance.
Misunderstood, magnetic resonance is very sad
1. Magnetic resonance is the same as other radiation inspections, there are radiation
Chief Physician, director of the Radiology Department of China University, said that the radiological examination mainly includes three categories: X-ray, CT, NM (MR). The X-ray and CT are radiated, but the magnetic inspection is no radiation. Because it mainly uses electromagnetic wave principles, the amount of electromagnetic wave is equivalent to the usual mobile phone and the energy released by the TV, so there is no radiation for the body, in fact, this is also its advantage.
2, the magnetic resonance price is expensive, you can do a CT.
Many people have selected CT and other inspections because of its “high on” The director of the winning red, in fact, some diseases, CT uncomfortable diagnosis, can only be magnetically resonant. Such as the central nervous system, spinal cord lesions, muscle soft tissues, head and neck tumors, primary myocardial diseases, aortic dissection, etc. have their irreplaceable roles.
3, put the bracket, can not do magnetic resonance check
Put the metal bracket, can you be magnetically resoned? The answer is negative, a large number of literature and clinical practice have confirmed that vascular stent surgery has been made in the past five years, and the nuclear magnetic inspection can be made for half a year. Partial early peripheral artery brackets may have weak magnetic properties, and there is a need for safety assessment for these weak magnetic peripheral artery brackets. However, there is a cardiac pacemaker heart bridge, a neurostat, and an intracranial silver clip, an eye-free metal foreign object, has been used in an arterial surgery (postoperative postoperative), cardiac surgery with artificial heart valve, Patients such as insulin pumps cannot be magnetically resonant imaging. Before checking, it is best to explain the medical history with the doctor.
4, installing a steel nail, and then vibrating with magnetic alliance.
After the fracture, there is a steel nail in the body. Experts pointed out that this also looks on the material. The material of the general alloy can be carried out, but if the surgical site, it may generate artifacts, affect the diagnosis. Moreover, for artificial joints, the metal implants such as titanium and cobalt-chromium molybdenum alloy are mainly used, but also in magnetic resonance, but also specifically for joint prosthesis, it is found to cause pain after surgery. .
Dougain, magnetic resonance is busy
1. Can pregnant women do?
Most image checks, in order to protect the baby from the belly of the pregnant woman from radiation, it is not recommended. But there is no radiation in magnetic resonance? Can pregnant women do? Dr. Wang Yuling, China University Hospital, did a certain answer. She introduced some high-risk pregnant women. Its diagnosis is very important. If there are abnormal pregnant women in large row, it can be combined with magnetic resonance, especially for placenta, etc. Due to the dangerous situation, early diagnosis, and do a good plan for the treatment of preemption.
2, can infants can do it?
Due to the advantages of magnetic resonance, the infant can also do, Dr. Wang Yuling introduces, especially for the central nervous problem, magnetic resonance examination. However, due to other images, there is a certain noise, and there will be a certain noise, it is generally recommended for the baby to check after taking the sedative or injecting the town. It is best to prepare the earplugs for the baby.
Note, there are many magnetic resonances.
All metal products
Middle School Radiology Qin Zhi Technician said that the magnetic resonance equipment (within 5 meters), with a strong magnetic field, strictly forbidden patients and accompanying families to bring all ferromagnetic items and electronic products, all kinds of magnetic storage media items close, with Inscription room. Some items are small metal treasures, but also pay attention. Such as metal buttons, metal zippers, metal on the bra, metal contraceptive ring is hidden, of course, key, watch, fake teeth, coins should be taken.
Tibetan metal substance
Not only can you see the metal items to be banned, but there are some items that have a metal material in this item, but also take it out. Such as plaster, warm baby, magnetic underwear, flammable and explosive products, corrosive chemicals, and moisture leakage liquid supplies are extremely dangerous. Warm baby will fever, mainly due to the heat generated by magnetically produced by metal debris. Qin Zhi introduced that patients who often encounter their baby on the waist or stomach will be reminded before the examination. If the baby is tested, the artifacts have seriously affect the results, and if the post is much, it may even be sucking to the machine.
Some women don’t make a don’t make makeup, but for those who want to do magnetic resonance, it can be seen in the sky. Qin Zhi explained that some cosmetics contain certain metals that will react with the magnetic field. Therefore, it is recommended that you should not make makeup, nail polish, antiperspirant, sunscreen, hair care, etc. don’t use it.
Tattoo, thick eyeline
Fashion people like tattoo, some love beauty also likes the eye line, but there is a certain hidden danger during the magnetic resonance examination. Qin Zhi explained that the pigments in the tattoo will heat, causing the skin to be irritated or even burns, covering it. If the skin is stimulating in the inspection, it should be stopped immediately. Therefore, before the examination, you should explain in advance with the doctor.
