【摘要】　目的　探討B型超聲檢查對聯體雙胎的診斷價值。　方法　回顧性分析2008年—2010年產前診斷為聯體雙胎的8例孕婦B型超聲聲像圖資料，總結其聲像表現。　結果　對稱性聯體雙胎8例，其中胸腹部聯體6例，頭部聯體2例。　結論　產前B型超聲檢查能為聯體雙胎的診斷提供重要臨床信息，并可做出不同類型的診斷。
【Abstract】　Objective　 To evaluate the value of B-scan ultrasound in diagnosing conjoined twins.　Methods　 Prenatal ultrasound diagnosis of eight cases of conjoined twins from 2008 to 2010 in West China Second University Hospital was retrospectively analyzed, and their ultrasonograhical performances were summarized.　Results　 Eight cases of conjoined twins with symmetry were diagnosed by B-scan ultrasound, including six with thoraco-omphalodidymus, and two with cephalodymus.　Conclusion　 Prenatal ultrasound can provide important information for diagnosis of conjoined twins, and perform differential diagnosis for different types.
