Many pregnant mothers will conduct four-dimensional color ultrasound to check the growth and development of the fetus during pregnancy, but sometimes because of the location of the fetus or too little amniotic fluid, etc., the four-dimensional color ultrasound cannot provide accurate diagnostic information, or the four-dimensional color ultrasound has been determined or cannot be determined when the central nervous system abnormalities, doctors recommend that pregnant women undergo magnetic resonance imaging.
Some pregnant women are frightened when they hear the three words of magnetic resonance: Is it a lot of radiation? Will such a test have an impact on the baby in my belly?!
Recently, Ms. Li, a pregnant woman, came to the Radiology Department of the Second People's Hospital of Hunan Province with the fetal four-dimensional color ultrasound report form and these problems to find Chief Physician Zhang Wei for consultation.
After listening to Ms. Li's confusion, Chief Physician Zhang Wei explained that it is certain that magnetic resonance examination has no ionizing radiation, it is a relatively safe examination method, and now more and more applications have been applied to the examination of the fetus, and there is currently a consensus in the world: for pregnant women after three months, it is possible to carry out this magnetic resonance examination with confidence.
However, for the early pregnancy within three months of the mother and fetus in the end whether there is an impact on this problem, the current research believes that for pregnant women in the early pregnancy of magnetic resonance examination will not significantly increase the risk of stillbirth and deformity, but we will be relatively cautious about the fetus within three months, to see how big the clinical demand, whether it is necessary to do magnetic resonance examination.
In addition, Chief Physician Zhang Wei reminded: It should be noted that when doing magnetic resonance examination, the diagnosis of some diseases needs to be clearly defined by an enhanced scan, and when the enhancement scan needs to be injected into the vein, this drug is called magnetic resonance imaging agent, which is temporarily not recommended for pregnant women, unless it is clinically believed that it must be done, from the perspective of treating diseases, the benefits are far greater than its risks, we recommend using it.
For all pregnant women in the middle and third trimesters, you can safely and boldly use magnetic resonance to screen the fetus and baby for eugenics!
Director Zhang also explained that sometimes pregnant women reach the third trimester of pregnancy at 36 weeks, for B ultrasound suspected placenta previa, the surgeon in order to better understand the placenta situation, judge whether there is placental implantation, prevent serious obstetric bleeding to make a full judgment, will also recommend MRI observation of the placenta, because the MRI examination range is large, the tissue resolution is high, can clearly observe the placenta located in the posterior wall of the uterus, it can be said that doing MRI examination can make the surgeon more confident to do the operation.
