三维超声在胎儿肢体畸形诊断中的应用

目的:探讨三维超声在胎儿肢体畸形诊断中的应用价值。方法:对31例产前常规二维超声检查怀疑胎儿肢体发育异常的病例进行三维超声检查,并与产后结果对照,比较二维、三维图像提供病变部位及细节的准确性。结果:所有病例都能够进行三维扫查并取得表面或最大透明三维立体图像,二维及三维超声对病变部位的检出率分别为81.1%(56/69)、94.2%(65/69),对病变细节的检出率分别为76.8%(53/69)、91.3%(63/69),差异均有统计学意义(χ2分别为7.111、8.100,P均<0.05)。结论:三维超声对胎儿肢体畸形的病变部位及细节具有较高的诊断价值。

Application of three-dimensional ultrasound in fetal limb deformities diagnosis

Aim:To analyze the three-dimensional(3D) ultrasound application value in fetal limb deformities diagnosis.Methods:According to the result of two-dimensional(2D) ultrasound,31 suspected cases of fetal limb abnormalities were selected and further checked by 3D.The results of 3D ultrasound and those of delivery,2D and 3D ultrasound in theparts of deformity and the accuracy of the details were compared.Results:All cases could be checked by 3D scanning,and 3D image of surface or maximum transparency were obtained.Diagnostic accuracy rates of 2D and 3D ultrasound were 81.1%(56 /69),94.2%(65 /69),and accuracy rates of lesion details were 76.8%(53 /69) and 91.3%(63 /69).There were significant differences between 2D and 3D results(χ2 = 7.111 and 8.100,P < 0.05).Conclusion:3D ultrasound could provide more diagnostic information of fetal limb and details,and is of great diagnostic value.
