體檢是孕媽孕期的必備功課，許多孕媽懷孕到一定的時(shí)期醫(yī)生都會讓孕媽去做四維彩超，或許有些孕媽會覺得平時(shí)已經(jīng)定期去做檢查了，四維彩超就沒必要再去做了，可是在生下一個不健康的寶寶后，悔不當(dāng)初。

有些孕媽很疑惑，什么是四維彩超呢?在孕期為什么一定要去做四維彩超，它的作用有哪些?在去做彩超的時(shí)候要注意哪些呢?下面，小編就來為大家詳細(xì)介紹一下。

Some pregnant women believe that it is unnecessary to have ultrasound screening if they follow routine prenatal checkups. However, ultrasound screening plays an irreplaceable and significant role in pregnancy, which should be valued by parents.

So, what’s 4D Ultrasound? What’s the function and what to be noticed? We will bring you details as follow. 

四維彩超的全稱是四維彩色超聲診斷儀，是世界上頂尖的彩色超聲設(shè)備。四維彩超能夠表面成像，更加清晰的篩查胎兒的四肢發(fā)育是否畸形，腦膜膨出，是否唇腭裂、脊柱裂等先天畸形，及早發(fā)現(xiàn)并及早做出解決方案。

4D ultrasound also called four-dimensional color Dopplor ultrasound diagnostic apparatus, which is the world's top color ultrasound equipment. It possesses surface image to high solution screening of deformity of fetal limbs, meningeal bulging, cleft lip and palate, spina bifida and other congenital malformations, which help to detect and take solutions earlier.

• 確定預(yù)產(chǎn)期

• Confirm the Expected Date of Delivery

一般在孕婦20周左右做四維彩超檢查，因?yàn)檫@個時(shí)候的彩超能比較準(zhǔn)確地推算預(yù)產(chǎn)期。

Generally, the expected date of delivery can be estimated accurately by 20 weeks’ scan.

• 查看胎兒的活動

• Observe Fetal Movement

可以檢查到胎兒在宮內(nèi)是否缺氧，肢體運(yùn)動、胎兒的吞咽動作等，能夠很好的看到胎兒在母體內(nèi)的活動狀況。 

It can clearly view the fetal movement inside your womb, such as fetal distress, swallowing, etc.

• 監(jiān)測胎兒生長發(fā)育

• Monitor Fetal Growth and Development

醫(yī)生解釋，檢測胎兒發(fā)育是根據(jù)測量胎兒的數(shù)值來判斷，如果低于第10百分位，或高于第90百分位的話，胎兒就是不正常的了。

According to doctor, the detection of fetal development is based on  fetal values. Lower than the 10th percentile or higher than the 90th percentile is deemed to be abnormal.

• 胎兒是否畸形

• Deformity or Not

彩超檢查是發(fā)現(xiàn)胎兒畸形的一個重要手段。一旦發(fā)現(xiàn)胎兒畸形，就可以及時(shí)終止妊娠。通常孕婦在妊娠22-26周做彩超是可以篩查胎兒是否畸形的，因?yàn)檫@個時(shí)段的胎兒各個器官都已經(jīng)發(fā)育成型，比較容易看出有沒有畸形，所以做彩超檢查十分重要。

Ultrasound scan is an important mean of detecting fetal malformations. If any malformation is detected, the gestation can be terminated in time. Usually 4D anomaly scan is arranged during 22-26 weeks, by then organs are developed and formed.

• 測量羊水量

• Measure Amniotic Fluid Volume

彩超可以比較準(zhǔn)確地測量羊水量。母體羊水量的多少對胎兒的發(fā)育非常的重要，因?yàn)檠蛩嗷蛘咛俣紩?dǎo)致胎兒畸形。在彩超中也可以清楚地了解胎盤的位置是否正常，胎盤是否有血管瘤的存在，是否成熟等，可以明確地診斷出前置胎盤，胎盤早剝等危險(xiǎn)情況的存在。

Color ultrasound can measure amniotic fluid volume accurately. It is critical to the fetal development as for too much or too little water would cause fetal malformation. However, ultrasound can show clearly the position of placenta, placenta hemangiomas, and its maturity etc., meanwhile, it can also diagnose of placenta previa and placental abruption as well.

1、一般整個孕期做三次四維彩超，懷孕的22~26周做四維彩超最佳，但是具體時(shí)間也是因人而異的。

1, Generally speaking, there should be three timings for ultrasound scan, and it’s better to be have anomaly scan during 22-28 weeks. But, it varies from person to person.

2、孕婦在22-26周的階段，做四維彩超不需要憋尿，也不需要空腹。孕婦只需要在規(guī)定的時(shí)間內(nèi)到醫(yī)院進(jìn)行檢查即可。

2, For 4D anomaly scan in 22-26 weeks, you don’t have to hold your urine or fasting, just make it according to your schedule.

3、在四維彩超檢查前，孕婦最好將自己的上衣和褲子分開穿。在四維彩超的檢查中，醫(yī)生主要是通過檢查的儀器，對胎兒當(dāng)前的面部發(fā)育，還有心臟，大腦，脊椎等有沒有存在發(fā)育缺陷的情況進(jìn)行一個檢查。

3, Before the scan, you should better separate your outfit by tops and pants. During the scan, the doctor mainly checks fetal’s current facial development, as well as the present development of heart, brain, and spine.

4、做四維彩超時(shí)，孕媽媽一定要保持良好的心態(tài)，整個檢查過程大概會持續(xù)20分鐘左右。

4, We encourage our mothers to stay in a fine mindset, as the whole process will last about 20 minutes.
