　　重慶安琪兒婦產(chǎn)醫(yī)院婦產(chǎn)醫(yī)生溫凱表示，B超屬于一種聲波傳導(dǎo)，不存在電離輻射和電磁輻射，而且醫(yī)學(xué)上使用的B超是低強(qiáng)度的，對(duì)人體組織沒(méi)有傷害，對(duì)胚胎來(lái)說(shuō)是安全的。</p> <p> 　　不過(guò)，雖說(shuō)B超對(duì)胎兒是安全的，但是過(guò)猶不及的說(shuō)法依然是有道理的。對(duì)于部分太過(guò)緊張?jiān)衅诜磻?yīng)的準(zhǔn)媽來(lái)說(shuō)，頻繁做B超檢查也是沒(méi)必要的。</p> <p> 　　對(duì)于孕期B超，究竟要做幾次，不能一概論之，應(yīng)以檢查目的為主。常規(guī)的必要次數(shù)當(dāng)然是不能少的，那么是否要增加B超次數(shù)則以醫(yī)生的檢查結(jié)果及建議，科學(xué)合理安排產(chǎn)檢即可。</p> <p> <strong>　　孕期需要做幾次超聲檢查</strong></p> <p> 　　6-7周（早孕檢查）：主要確認(rèn)孕周，看究竟是宮內(nèi)妊娠還是宮外孕，單胎還是雙胎（確認(rèn)絨毛膜性）或多胎。</p> <p> 　　11-14周（NT檢查）：主要是檢查NT和抽血進(jìn)行早孕期唐氏篩查。</p> <p> 　　20-24周（系統(tǒng)超聲檢查）：主要是胎兒的大畸形篩查，了解胎兒是否存在大的結(jié)構(gòu)缺陷。</p> <p> 　　32周左右（常規(guī)檢查）：主要是監(jiān)測(cè)胎兒生長(zhǎng)發(fā)育情況，查驗(yàn)胎兒是否有生長(zhǎng)受限、羊水及臍帶等情況等。</p> <p> 　　37周左右（常規(guī)檢查）：判斷胎兒發(fā)育情況、羊水量、胎盤成熟度、有無(wú)臍帶繞頸、胎位；測(cè)量胎兒雙頂徑、頭圍、腹圍、股骨長(zhǎng)來(lái)估算胎兒體重，以確認(rèn)分娩方式。</p> <p> <strong>　　三維、四維彩超有必要做嗎</strong></p> <p> 　　三維彩超是在二維彩超的基礎(chǔ)上增加了另外一個(gè)空間軸，可以形成靜態(tài)的立體圖像。</p> <p> 　　四維彩超是在三維彩超圖像的基礎(chǔ)上加上時(shí)間維度參數(shù)，可以實(shí)時(shí)觀察胎兒動(dòng)態(tài)的活動(dòng)圖像。有的準(zhǔn)爸媽會(huì)把四維圖像珍藏起來(lái)當(dāng)作寶寶的第一張照片。但無(wú)論是三維還是四維，做不做主要看準(zhǔn)爸媽們自己的選擇。（重慶安琪兒婦產(chǎn)醫(yī)院供稿）</p>
