目的：探讨二维及三维超声联合磁共振诊断胎儿蝴蝶椎的价值。方法：回顾性分析产前使用二维、三维超声和磁共振诊断胎儿蝴蝶椎的病例，追踪随访结果。结果：产前诊断蝴蝶椎36例，其中10例合并其他畸形。对比出生后随访结果，使用二维超声、三维超声及磁共振的诊断准确率分别为69.4%、94.4%、78.8%。结论：二维、三维超声及磁共振在诊断胎儿蝴蝶椎时各具优势与不足，联合多种检查方法可以提高胎儿蝴蝶椎的诊断信心。不合并其他畸形及染色体异常的蝴蝶椎预后良好。
Abstract
Objective: To explore the value of 2D and 3D ultrasound combined with MRI in the diagnosis of fetal butterfly vertebrae. Methods: The cases of fetal butterfly vertebrae diagnosed by 2D, 3D ultrasound and MRI were retrospectively analyzed, then the follow-up results were collected. Results: Thirty-six cases of butterfly vertebrae were diagnosed prenatally, of which 10 cases were complicated with other deformities. Compared with the results of postnatal follow-up, the diagnostic accuracy of 2D, 3D ultrasound and MRI were 69.4%, 94.4% and 78.8%, respectively. Conclusions: 2D, 3D ultrasound and MRI have their own advantages and disadvantages in the diagnosis of fetal butterfly vertebrae. The combination of these examinations can improve the diagnostic confidence of the disease. The butterfly vertebrae without other deformities and chromosome abnormalities has good prognosis.
