【摘要】　目的　探讨B型超声检查对联体双胎的诊断价值。　方法　回顾性分析2008年—2010年产前诊断为联体双胎的8例孕妇B型超声声像图资料，总结其声像表现。　结果　对称性联体双胎8例，其中胸腹部联体6例，头部联体2例。　结论　产前B型超声检查能为联体双胎的诊断提供重要临床信息，并可做出不同类型的诊断。
【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.
