目的：通过分析3l例胎儿前腹壁缺损在快速磁共振扫描序列中的表现，探讨MRI在胎儿前腹壁缺损诊断中的价值及其对临床治疗的指导作用。方法：回顾性分析31例胎儿前腹壁缺损的MRl图像，并与产前超声或分娩后结果进行比较。结果：MRI正确诊断所有31例胎儿前腹壁缺损，其中脐膨出19例，腹裂12例。19例脐膨出胎儿中伴发畸形7例(7/19)，12例腹裂胎儿中伴发畸形3例(3/12)。在脐膨出胎儿组中5例经MRI诊断后实行引产终止妊娠，14例活产，其中5例经手术等治疗后死亡，9例存活；在腹裂胎儿组中3例经MRI诊断后实行引产终止妊娠，9例活产，其中2例经手术等治疗后死亡，7例存活。结论：快速MRI在胎儿前腹壁缺损及相关伴发畸形的诊断具有重要作用，是对产前超声的重要补充。%Objective:To study the MRI manifestations of fetal anterior abdominal wall defect ( AWD) with fast MR sequences ? In order to evaluate the role of MRI in the diagnosis and treatment guidance in clinical practice of this disease entity. Methods:31 prenatal fetuses with anterior AWD including omphalocele (n=19) and gastroschisis (n=12) diagnosed by prenatal ultrasounography (US) and MRI were retrospectively analyzed. The MRI findings were correlated with US or postpartum findings. Results: All fetal anterior AWD could be detected antenatal with MRI. Accompanied malformations in fetuses with omphalocele were assessed in seven cases (7/19,36. 8%),whereas accompanied malformations in gastroschisis were assessed in 3 cases (3/12,25%). 14 fetuses with omphalocele were born alive,5 of them died after treatment,nine babies survived ;five cases had pregnancy terminated after the diagnosis of AWD. As for the 12 fetuses with gastroschisis, two of them died after treatment, 7 survived. Three cases with gastroschisis had pregnancy terminated. Conclusion: Fast MRI plays an important role in the diagnosis of fetal anterior AWD and accompanied malformation,it is a significant complemen-tal approach of prenatal ultrasonography.
