Throughout the pregnancy, both spouses were immersed in mixed emotions of joy and worry. They rejoice in the arrival of the little angel, and the pregnant mother feels the changes in the child every day and is full of expectations for the future.
On the one hand, we are worried about the growth and development of the baby, after all, separated by a layer of belly and uterus, we cannot judge the health status of the fetus through the naked eye.
Therefore, after pregnancy, in order to ensure that the fetus and pregnant women are in the best state, fully understand the growth and development of the fetus, and calculate the expected date of delivery, expectant mothers need to seek medical treatment regularly for related examinations, the most commonly used examination item is ultrasound.
Because it uses the principle of ultrasonic reflex imaging, there is no radiation, so it will not affect the fetus, but also can observe the fetal situation at various stages, such as determining whether it is an intrauterine pregnancy in the first trimester, determining whether the fetal development is healthy in the second trimester, observing the fetal position in the third trimester, the status of the placenta and estimating the expected date of delivery, etc., all of which require B ultrasound assistance.
However, ultrasound also has its shortcomings, because it cannot pass through the skull of the fetus, and the visual field of the examination is relatively small, and the results may not be too accurate for obese pregnant women.
At this time, if the ultrasound is abnormal, but can not directly determine the specific problem, in order to ensure the health of the fetus, it is necessary to assist other tests for diagnosis, such as mriori resonance is one of them.
So the question is, can pregnant women have an MRI? Will it affect the health of the fetus?
MRI is actually a new imaging diagnostic technique developed using the principle of NMR (mainly caused by the spin motion of the nucleus).
It can examine and diagnose multiple organs throughout the body, such as the brain, thyroid, liver and gallbladder, spleen and pancreas, kidneys and adrenal glands, reproductive organs, prostate and other parenchymal organs, or the heart, large blood vessels, etc., can find the problem through MRI.
Compared with other imaging examination items, MRI has multiple points such as fast scanning speed, high tissue resolution, clearer images, etc., and its imaging parameters are more, which can help doctors see early lesions that are not easily detected, and it has become an early screening tool for malignant or benign tumors, heart disease, and cerebrovascular disease.
In the clinical view, NUCLEAR magnetic resonance uses the principle of magnetic field imaging, it does not have any radioactivity, so there is no harm to the human body, it is a very safe means of examination.
So far, there have been no reports of the harm caused by MRI tests around the world, nor have there been any genetic mutations or chromosomal aberrations in patients as a result of this test. Therefore, for pregnant women and fetuses, MRI is also a relatively safe means of examination.
Moreover, during the examination, magnetic resonance can perform detailed scans of the fetal brain and central nervous system, which can obtain more accurate results.
In addition, the imaging of magnetic resonance examination is more intuitive and the resolution is higher, which allows doctors to more intuitively evaluate the development of the fetus, and can also scan any section during the examination process, which can be accurate to the various organs and limbs of the fetus.
Written at the end: In a word, magnetic resonance imaging is not radioactive, it is a safer means of inspection.
If a pregnant woman finds that the fetus may be abnormal during ultrasound, but cannot be accurately diagnosed, the next step of magnetic resonance imaging should be performed according to the doctor's recommendation so that the specific situation of the fetus can be fully understood.
