四维超声骨骼模式在胎儿半椎体畸形中应用价值 　　摘要：目的 探讨二维超声结合四维超?在胎儿半椎体畸形中的应用价值。方法 应用二维超声及四维超声骨骼模式对8例半椎体病例进行图像分析。结果 二维超声显示5例发生在腰段，3例发生在胸段；胎儿脊柱旁矢状切面显示病变处椎体骨化中心缺失或模糊，脊柱冠状切面显示病变处脊柱侧弯或成角；四维超声骨骼模式显示病变处椎体骨化中心小或缺失，对侧骨化中心代偿性增大，直观动态的显示脊柱侧弯或成角畸形，通过肋骨及脊柱的关系可以清晰的定位病变椎体，图像逼真。结论 四维超声骨骼模式能在二维超声诊断胎儿半椎体畸形的基础上提供更多病变椎体的诊断信息，具有重要的临床参考价值，是二维超声影像诊断的必要补充。 　　关键词：四维成像；骨骼模式；胎儿；脊柱；半椎体畸形 　　中图分类号：R445.1 文献标识码：A 文章编号：1006-1959（2017）24-0041-03 　　Application Value of Four-dimensional Ultrasound Bone Pattern in Fetal Semi Vertebral Deformity 　　ZHANG Li-sha，ZHANG Ling-mao，HAO Xiao-ying，ZHANG Dan，GAO Yan 　　（Department of Ultrasound，Zigong Maternal and Child Health-Care Hospital，Zigong 643000，Sichuan，China） 　　Abstract：Objective To investigate the diagnostic value of two-dimensional ultrasound combined with four-dimensional ultrasound in fetal hemivertebra.Methods Two dimensional ultrasound and four dimensional ultrasound image analysis of skeletal pattern in 8 cases of hemivertebra cases.Results Two dimensional ultrasound showed 5 cases in lumbar，3 cases occurred in the thoracic spine；fetal parasagittal plane display lesions vertebral ossification center is absent or vague，coronal surface display lesions of spinal scoliosis or angle；Four dimensional ultrasound skeletal lesions vertebral ossification center pattern showed small or absent，the ossification center side compensatory increase，intuitive display dynamic scoliosis or angular deformity，through the relationship between the ribs and spine vertebral lesions can clear positioning，lifelike images.Conclusion Ultrasound diagnostic information of four-dimensional skeleton model can provide more vertebral two dimensional ultrasonic diagnosis of fetal hemivertebra，has important clinical reference value，is a necessary complement to two-dimensional ultrasound imaging diagnosis. 　　Key words：Four dimensional imaging；Skeletal pattern；Fetus；Spine；Hemi vertebral deformity 　　胎儿半椎体畸形是一种少见的脊柱发育畸形，其预后较为复杂，产前超声诊断对了解病情及明确临床诊断，选择终止妊娠或产后早期治疗有重要意义[1]。文献报道[2-3]目前胎儿半椎体畸形多采用二维或三维超声检查，二
