产前超声联合磁共振对胎儿颅内出血的诊断价值

Diagnostic value of MRI combined with fetal prenatal ultrasound for intracranial hemorrhage

目的探讨产前超声联合磁共振检查在胎儿颅内出血诊断中的应用价值。方法回顾分析2010-10～2012-10在我院经产后MRI证实的32例胎儿颅内出血病人的产前超声检查资料,本组病人定为超声组;2010-10～2012-10在我院经产后MRI证实的40例胎儿颅内出血病人的超声联合磁共振的检查资料,本组病人定为联合组。比较二组检查方法对疾病的诊断准确率。结果超声组确诊的32例患者中,超声检查提示胎儿颅内出血者28例,准确率为87.5%;联合组确诊的40例患者中,联合检查提示胎儿颅内出血者39例,准确率为97.5%。两组比较差异具有统计学意义（P〈0.05）。结论超声联合磁共振诊断胎儿颅内出血的诊断准确率高,值得推广应用。

Objective To explore the value of Doppler ultrasound combined with magnetic resonance （MRI）in the diagnosis of fetal in- tracranial hemorrhage. Methods The prenatal ultrasound data of 32 cases of fetal intracranial hemorrhage （ ultrasound group） con- firmed by postpartum MRI from October 2010 to October 2012 were retrospectively analyzed. The prenatal ultrasound and MRI data of 40 cases of fetal intracranial hemorrhage（ combination group）confirmed by postpartum MRI from October 2010 to October 2012 were retrospectively analyzed. Results In ultrasound group, 28 cases of intracranial hemorrhage was detected by ultrasound, and the ac- curacy rate was 87.5%. In combination group, 39 cases of intracranial hemorrhage was found, and the accuracy rate was 97.5%. There was significant difference between the two groups （ P 〈 0. 05 ）. Conclusion MRI combined with ultrasound could have high diagnostic accuracy for fetal intracranial hemorrhage, and should be widely applied.
