二维彩超看男女准吗

二维彩超是孕期检查的一项必要工作。很多妈妈都想通过二维彩超来判断宝宝性别，但是她们又经常问到但是二维彩超看男女准吗？妈妈的心情是可以理解的。今天小编就给大家揭秘，通过二维彩超看性别到底准不准？
 
怀孕初期做二维彩超是看不出胎儿性别的。怀孕初期胎儿生殖器官并没有发育完全，这个时候不能判断是男是女。一般要到4个月以上就能看出二胎的性别，准确率约85%，但是通过B超来看胎儿性别是不符合道德违法的。
 
很多人会通过孕囊的大小来判断是男是女。一般说来，如果孕囊的形状像茄子，或者是呈长条状的，则男宝宝的可能性更大，而如果孕囊是椭圆形或圆形的，很可能就是个女宝宝了。
 
通过数据得出的结果是，如果长和宽的相差在一倍以上男宝宝可能性大，长和宽相等女宝宝可能性大。
 
但是任何数据都不是100%准备，妈妈想早点知道宝宝性别的心情能理解，男女都一样，妈妈只要保持愉快的心情迎接宝宝的到来。
 

二维彩超检查什么

随着科技的发展，二维彩超已成为孕期检查的一项必不可少的工作，让妈妈了解胎儿的发育情况，而很多妈妈对二维彩超检查什么并不是很了解，只是知道必须要做这项工作，今天小编就告诉各位妈妈答案。
 
二维彩超是由高清晰度的黑白B超加上彩色多普勒技术的检查手段，可以通过影响了解胎儿不同孕周的发育情况，并及早发现二胎是否异常发育。
 
二维彩超是立体成像，主要是以图片形式观察，仅限于局部观察，清晰度及检测度都不及四维彩超，但是高于黑白B超，虽然比较模糊，但是能满足一般的产检要求。
 
怀孕期间任何时间都可以做二维彩超，但是排畸检查最好是在怀孕24-28周之间。这个时候胎儿器官发育基本完成，而又不至于发育过大影响彩超检查结果。
 
二维彩超提供的是一个平面影像，通过影像不仅可以判定胎儿月龄、大小，还可以看出胎盘情况，能分析胎儿的大致的发育情况，确定胎儿的发育是否正常。
 
多胞胎或者高危妊娠通过二维彩超也可以看出。所以，孕期做二维彩超是非常必要的。它可以帮助妈妈随时了解宝宝的发育情况。
 

二维彩超可以排畸吗

怀孕是一件高兴的事情，高兴之余妈妈的担心的问题又来了。孕期每个妈妈都会高度关注宝宝的发育情况，担心宝宝畸形发育，所以孕期都会通过做二维彩超来排畸。那么，二维彩超可以排畸吗？这个问题大多数人不知道，下面小编就给大家简单介绍一下。
 
影响二胎畸形的因素有两个，一是遗传因素，二是外界因素。一般遗传畸形的概率很低，几乎可以排除。导致二胎畸形的最大因素就是后天发育造成。
 
孕期前3个月内非常关键。这2个月内如果孕妇得了病毒性感冒，是最有可能导致畸形的。通过二维彩超，可以判断二胎是否畸形发育。
 
二维彩超可以通过血流信号可以判断出脐带绕颈几周。一般在孕期24-28周做排畸检查，那时候宝宝皮肤是透明的，可以用二维彩超看清楚心脏发育内脏器官是否完整，五官发育是否正常。
 

二维彩超排畸的好处

随着医疗科技的迅猛发展，二维彩超已经能够通过影像技术检测出畸形儿，大大降低了畸形儿的出生比例。所以，二维彩超排畸筛查成为一项至关重要的检查。今天小编就给大家介绍一下二维彩超排畸的好处。
 
二维排畸筛查一般会安排做两次，第一次在孕20-24周，主要是观察宝宝的头部、脊柱、心脏、肺、胃肠、双肾、膀胱、外生殖器、四肢，看看宝宝是否存在较大的畸形。第二次在孕28-32周，重点观察宝宝的鼻唇部和心脏，发现唇腭裂(即兔唇)、心脏的畸形(即先天性心脏病)。其中第一次排畸筛查很重要，能够检查出胎儿是否有较大的畸形问题。
 
1、通过二维彩超可以准确的知道孕妇的羊水量。羊水过多或过少，都可能预示是不是有胎儿畸形，是不是有先天性疾病等异常。
 
2、二维彩超可以测量出胎儿的双顶径、头围、腹围及胎儿股骨的长度等，通过这些数量可以知道胎儿的发育情况。
 
3、通过二维彩超可以判断胎儿的胎儿位置是否正常，胎盘有无血管瘤的存在等问题。
 
以上就是二维彩超排畸的好处。所以，孕期做二维彩超是一项不可少的检查工作。妈妈们一定要高度重视，定期做检查。
 

二维彩超注意事项

大家都知道孕期做二维彩超可以清楚的知道胎儿的发育情况。为了让二维彩超更准确的检测数据，我们必须要注意什么？一起来看看二维彩超的一些注意事项。
 
1、二维彩超是一项必要工作，通过二维彩超可以得知孕妇的羊水量情况，判断胎儿的发育情况，一定要积极配合检查。
 
2、做二维彩超尽量采用最小的辐射强度和最短的时间，获取必要的诊断资料，每次检查时间不超过5分钟，超声仪器的功率应小于10毫瓦/平方厘米。
 
3、不可通过二维彩超来检查胎儿性别，长时间照射胎儿睾丸会对精原细胞产生损伤。
 
4、做二维彩超时要已最快的时间检测，不可延长辐射时间，时间过长辐射会刺激胎儿的发育。
 
5、二维彩超检查不可做太多，一般无特殊情况，整个孕期做1-2次二维彩超检查即可。很多人认为二维彩超做的越多越好，可以时时了解宝宝的发育情况，这个观念是错误的。妈妈们一定要正确认识二维彩超。
