Zhumadian News (Reporter Wang Jie) Ms. Hu has been pregnant for 32 weeks, and regularly conducts a production inspection.But one day, the doctor found that her baby was a little different. After the ultrasound examination, the expert suggested that another magnetic resonance examination. Will she think of hurting the baby?
What is this inspection?Is there any radiation?Why let pregnant women do this test?What should I pay attention to? Today, the Dr. MRI of the Central Hospital of Zhumadian City led everyone to unveil the mysterious veil of the fetal magnetic resonance examination!
Is there any radiation of fetal magnetic resonance examination?
Fetal magnetic resonance (MRI) does not have ionized radiation or rays!And inspection does not cause any radioactive damage.
Fetal magnetic resonance not only does not have radiation, but also many B -ultrasound functions:
For example, high resolution, large field of vision, repeated examination, and clearer the condition of the central nervous system of the fetus can be used. These can be used for fetal assessment and congenital dysplasia diagnosis.
Why do pregnant women have done a magnetic resonance?
As we all know, fetal ultrasound examination is the preferred method of fetal imaging examination. The fetal ultrasound examination is fast, real -time, economy, affordable, accurate, and irreplaceable advantage.However, every medical examination is not a panacea. The B -ultrasound is limited to a certain extent. In many cases, the information obtained only by ultrasound is not sufficient, and other inspection methods need to be improved.Fetal magnetic resonance imaging (MRI) is one of the important auxiliary examination methods of ultrasound examination, and it is an important supplementary method for prenatal imaging examinations.
Precautions for fetal magnetic resonance examination
Since the fetal magnetic resonance has so many advantages, can you do MRI directly in place?
No, no no!Don’t hear the fetal magnetic resonance, you feel that it can be done at any time.
On the one hand, completing the B -ultrasound check -up on time can meet the needs of most pregnant women.
On the other hand, although research shows that the magnetic resonance in the early pregnancy (before 12 weeks) did not show that it was harmful to the fetus, the mRI examination in the early pregnancy was unnecessary.Some of the central nervous system structure of the fetus is relatively late. Therefore, the timing of fetal MRI examination is recommended to be in the 20th gestational week and later.
The advantage of fetal magnetic vibration imaging
Central Nervous System
Fetal magnetic resonance is the most widely used in the central nervous system.Fetal magnetic resonance is very reliable for the diagnosis of brain lesions and spinal cords. Therefore, it is recommended to perform fetal magnetic resonance examinations when prenatal ultrasound detection or suspected fetal central nervous system abnormalities.
Fetal magnetic resonance also has high application value in the diagnosis of fetal lung deformity. It can show the development of the lung tissue and provide more prognosis related information to help doctors formulate a reasonable treatment plan.
In some fetal heart disease, such as congenital heart large vascular malformation, pericardial effusion, pericardial cyst, heart diverticulum, heart horizontal muscle tumor, etc., the fetal heart magnetism has a better diagnosis effect.
Due to the advantages of high magnetic resonance vision and high soft tissue resolution, there are more comprehensive observations for some abdominal diseases, such as fetal digestive tract deformities, urogenital deformed, abdominal wall malformations, and abdominal tumors.
Fetal facial deformities, such as lip cracks, cleft palate, dysplasia or lack of eyeballs, etc., can be further confirmed and supplemented through the fetal magnetic resonance, and you can also find whether other related deformities are merged.
Li Hong, director of the MRI of the Middle Hospital of the City Center, reminds you of expectant mothers that there will be a certain noise when the magnetic resonance examination is checked. During the examination, the pregnant woman will wear anti -noise earmuffs to reduce the discomfort caused by noise.There are no reports of fetal magnetic resonance imaging examinations that cause damage to the fetus. Please rest assured that the mothers are assured.
