不同初始切面在三维超声检查胎儿裂隙畸形的误差与区别
【摘要】 目的 探讨不同初始切面在三维超声检查裂隙畸形时的误差与区别.方法 应用GE Voluson E8超声诊断仪,采用静态三维成像模式,对金属片上的圆孔与长孔进行超声三维重建,对所得三维孔图像进行测量与实际数值对比；对7例唇裂或唇腭裂畸形胎儿及3例标本进行三维超声重建,初始切面分别与胎儿唇裂或唇腭裂裂隙平行和垂直,得到图像裂隙宽度进行对比.结果　圆孔纵径在探头与金属片距离在30～90mm、长孔初始切面垂直时距离在25～95mm时与实际值比值在0.90～1.10之间；圆孔横径在距离50～75mm、长孔初始切面平行时在距离50～90mm时与实际值比值在0.90～1.10之间.其余距离时与实际值比值小于0.90.初始切面不同所得胎儿唇裂或唇腭裂裂隙宽度不同,在分别与裂隙长轴平行和垂直所得数据不同,进行配对t检验后认为初始切面与裂隙垂直时所得数据较大.结论　只有在探头与所检查对象在50～75mm之间时图像才接近于真实图像.在距离为30～50mm、75～90mm之间时,三维重建裂隙图像较正常变瘦,即裂隙宽度更小.

Different initial cut in 3 d ultrasound examination of the fetal malformation error and difference between the crack
【 abstract 】 objective to explore different initial cut in 3 d ultrasound examination of the fracture of the error and difference between deformity. Method GE Voluson e8's ultrasound diagnostic instrument, static 3-d imaging mode of the round hole and metal long hole for ultrasonic 3 d reconstruction of income, 3 d image with the actual measurement hole numerical comparison, 7 cases of harelip or cleft malformation fetus and 3 cases of specimens were three-dimensional ultrasound reconstruction, the initial cut respectively with the fetus harelip or cleft fissure running parallel and perpendicular to crack width image comparison get. Results the hole of the longitudinal diameter in the probe and the metal distance in 30 to 90 mm long, vertical hole cut in initial from 25 to 95 mm with actual value ratio was between 0.90 and 1.10; Round hole diameter distance in the 50 to 75 mm, long hole cut in initial parallel 50 to 90 mm distance with the actual value ratio was between 0.90 and 1.10. The rest with the actual distance value ratio is less than 0.90. The initial cut different income fetal harelip or crack width, in different cleft palate respectively and fissure long axis parallel and perpendicular data from different, undertake matching t test that after the initial cut and fissure vertical income data is bigger. Conclusion in the probe and the only examine objects in 50 ~ 75 mm to close to true image when image. In the distance for 30 to 50 mm, 75 ~ 90 mm, 3 d reconstruction fissure image than normal thin, crack width is smaller.
