摘　　要：目的:探讨三维超声成像技术在产前胎儿畸形筛查中的应用价值。方法:应用二维及三维超声检查98例合并畸形的胎儿,比较两者对胎儿畸形的诊断符合率,并评估两者提供的诊断信息有无差别。结果:98例胎儿中,经引产和随访共发现胎儿结构异常142处,二维超声能确诊并与引产及追踪随访结果相符的有115处(81.0%),三维超声则为133处(93.7%),两者比较差异有统计学意义(χ2=10.31,P<0.05)。三维超声检出的133处胎儿畸形中,70例(52.6%)三维超声可提供更丰富诊断信息,特别在评价胎儿颅面部、脊柱四肢及体表畸形时检出率高于二维超声。结论:三维超声成像技术可作为二维超声成像技术的补充,能提供更多的诊断信息,具有临床实用价值。Objective： To evaluate the application value of three-dimensional ultrasonography（3DUS） in diagnosing fetal malformations.Methods： Both 2DUS and 3DUS were used to examine 97 pregnant women with fetal malformations.The diagnostic rate of 2DUS and 3DUS were compared,and the diagnostic information provided by the two methods was evaluated.Results： One hundred forty-two malformations were discovered by induced labor and follow-up in 98 fetuses of 97 pregnant women.In 115 malformations（80.9%） 2DUS made the affirmative diagnoses in accordance with the results;however,133 malformations（93.6%） were made by 3DUS.The difference between them was statistically significant（χ2=10.31,P0.05）.In 70（52.6%） cases of 133 malformations discovered by 3DUS,there were more diagnostic information provided by 3DUS than 2DUS.3DUS had particular advantages over 2DUS in evaluating the fetal malformations of cranium-face,spine-extremity,and body surface.Conclusion： The diagnostic rate of 3DUS is higher than that of 2DUS,and 3DUS provides more diagnostic information in evaluating fetal malformations.Therefore,3DUS has practical clinical value in prenatal diagnosis.
