超声检查联合核磁共振成像对胎儿颅脑畸形的诊断价值

目的探讨超声检查联合MRI在胎儿颅脑畸形诊断中的应用价值。方法对行超声检查及行MRI检查的12例颅脑畸形的胎儿进行对比分析，并与出生后、引产后及外院检查结果进行比较并评价其准确性。结果12例颅脑畸形的胎儿超声检查明确诊断8例，误诊3例，漏诊1例；MRI明确诊断11例，漏诊1例。结论超声检查是胎儿颅脑畸形筛查的必选检查，MRI检查可以作为超声检查补充诊断方法，两者联合在指导孕妇确定是否继续妊娠方面具有重要的指导意义。

Ultrasonography and magnetic resonance imaging for diagnosis of fetal skull brain deformities

Objective To evaluate ultrasonography combined with magnetic resonance imaging（MRI） diag- nosis value for fetal brain deformities. Methods The results of uhrasonography and MRI was analysied in 12 fetuses with deformities, which were compared to postnatal, autopsy or other hospital inspection results and evaluated the accu- racy. Results In 8 cases,the diagnoses established by ultrasonography were correct. 3 cases were misdiagnosed by uhrasonography, 1 case was missed the diagnosis. In 11 cases, the diagnoses established by MRI were correct and 1 case was missed the diagnosis. Condusion Ultrasonography must be choosed in diaguosising fetal skull brain deformities, MRI was supplement to uhrasonography in complicated pregnancies. The combination of ultrasonography and MRI have an important value in guiding pregnant women to determine whether or not to continue the pregnancy.
