When should ultrasound screening be done?

People often hear about B-ultrasound examinations. When people feel unwell or need regular physical examinations, it is necessary to go to the hospital for scientific examinations. In this process, they will often come into contact with B-ultrasound. In fact, B-ultrasound is the most popular examination method in medicine today. It can examine many parts of the human body. For example, after pregnancy, it is necessary to do regular B-ultrasound screening, which is very important.

When is the best time to do ultrasound screening?

First, do an ultrasound when the pregnancy is confirmed in the early stage. It is best to wait until 50 days after the menstrual period ends. As long as the menstrual cycle is normal, you can basically see the gestational sac, embryo and fetal heart rate at this time.

Between 18 and 24 weeks of pregnancy, go for a 3D B-ultrasound to rule out fetal anomalies. At around 32 weeks, there will be a two-dimensional B-ultrasound, which is mainly to check the baby's development.

There will be another B-ultrasound when the baby is about to be born, which is usually done after 36 weeks. Generally speaking, these four times are basically necessary.

Some pregnant women have more frequent B-ultrasound examinations during pregnancy, which depends on their physical conditions. If any of the examinations are not up to standard, they need to undergo more B-ultrasound examinations for reexamination.

B-ultrasound examination precautions

Heart: When undergoing a cardiac ultrasound examination, you should rest for a while, take off your shoes, lie flat on the examination bed, unbutton your shirt, expose your chest, and let the doctor examine it.

Spleen: No special preparation is required for simple examination of the spleen, but the spleen will shift backward and upward after a full meal, affecting the imaging, so it is better to examine the spleen on an empty stomach.

Generally, pregnant women need to undergo four B-ultrasound examinations during pregnancy. Under normal circumstances, the best time to undergo B-ultrasound examinations is 50 days after amenorrhea, 18-24 weeks of pregnancy, 32 weeks, and 36 weeks of pregnancy. If there are any emergencies, multiple B-ultrasound examinations may be required. I hope all expectant mothers pay attention!

B-ultrasound during pregnancy to check fetal health

The first B-ultrasound during pregnancy is a big event during pregnancy. While I can't wait to see my baby, I can't help but worry if something goes wrong. B-ultrasound examination can help doctors observe the development of the fetus, determine the size of the fetus and the relatively accurate due date of the expectant mother. Therefore, ultrasound examination is of great significance in ensuring the health of the fetus and the smooth delivery of the expectant mother. But in addition to B-ultrasound, there are many other necessary prenatal examinations.
