Can pregnant women do MRI?

As we all know, women need to have regular prenatal checkups after they become pregnant. However, general prenatal checkups usually do not have a big impact on the fetus. However, some pregnant women need to do MRI examinations due to some special circumstances. Many people know that the radiation from MRI is very large. Therefore, some pregnant women are reluctant to do MRI examinations, fearing that it will affect the baby's health. Can pregnant women do MRI examinations?

Can pregnant women do MRI?

Magnetic resonance imaging is also a type of radiation that scans the entire body in all directions. It is not advisable for pregnant women to do this as it may affect the development of the baby. We recommend that you consider it carefully.

With the development of technology, pregnant women can now undergo MRI examinations, but it is generally not done in the early stages of pregnancy and is usually done in the late stages of pregnancy! The technology is now very mature and has no effect on the fetus! MRI is not a particularly commonly used screening method, it is mainly used to solve special problems raised by ultrasound examinations.

The main purpose of doing MRI on babies is to examine the fetal nervous system and neck masses that may compress the trachea, including ventriculomegaly, midline structural abnormalities, posterior cranial fossa abnormalities, cerebral cortex abnormalities, and screening for familial encephalopathy such as tuberous sclerosis and corpus callosum dysgenesis.

When is the best time to check MRI for pregnant women?

However, the choice of time for MRI examination is very important, otherwise you will be wasting money and suffering without solving the problem. It is generally believed that the fetus in the stage of fetal organ formation, that is, the first 12 weeks of pregnancy, is very sensitive to noise and heat during MRI and is affected to a certain extent. The imaging contrast of the development of the fetus' organs under MRI is very poor before 7 months, so the effect of MRI before 28 weeks is not as good as ultrasound examination. In other words, ultrasound examination before 28 weeks can observe the fetus more clearly.

After 28 weeks, all organs of the fetus can be well imaged under MRI. At the same time, ultrasound cannot clearly observe lesions in the fetal head due to calcification of the fetal head bones. At this time, MRI is the best way to examine the fetal head. Therefore, the choice of time for NMR examination is very important.

In fact, MRI can be performed in the late pregnancy, and it has little effect on the fetus. Therefore, an MRI can be done after 28 weeks of pregnancy, at which time the condition of the fetus can be clearly seen and the problems raised by B-ultrasound can also be solved. The fetus's condition can be clearly seen, so pregnant women should pay attention to MRI examinations and not be afraid to seek medical treatment!
