超声联合MRI对胎儿中枢神经系统疾病诊断分析

The Diagnosis and Analysis of Fetal Central Nervous System Disease by Combined Use of Ultrasound and MRI

目的探讨产前超声联合MRI检查对胎儿中枢神经系统疾病的诊断价值.方法回顾性分析在本院经产前超声检出中枢神经系统疾病并进一步接受MRI检查的胎儿共46例,分析MRI与超声诊断的符合、补充及纠正情况.结果在46例病例中,产前超声做出明确诊断27例,其中有23例与MRI诊断相符,诊断符合率为85.2%;余19例超声提示可能存在病变但未做出明确诊断的病例中,MRI补充诊断14例,余5例MRI未发现明确异常并经随访证实.结论超声与MRI对胎儿中枢神经系统疾病诊断具有较高的符合率,对超声不能明确诊断的疾病,MRI可作为重要的补充手段.

Objective To investigate the value of prenatal ultrasound combined with MRI in diagnosis of fetal central nervous system disease. Methods The data of 46 cases of fetuses with central nervous system disease detected by ultrasonography and further MRI examination in the hospital were retrospective analyzed. Analyze the compliance, supplementation and corrections results of ultrasonography and MRI. Results Among the 46 cases, prenatal ultrasound made a definite diagnosis of 27 cases, of which 23 cases were consistent with MRI diagnosis, the diagnostic coincidence rate was 85.2%;among the remaining 19 cases of ultrasound suggesting that there may be lesions but no clear diagnosis, there were 14 cases of MRI supplementary diagnosis, and the remaining 5 cases of MRI did not find clear abnormalities and were confirmed by followup. Conclusion Ultrasound and MRI has a high coincidence rate for the diagnosis of fetal central nervous system diseases. MRI can be used as an important supplement for diseases that cannot be clearly diagnosed by ultrasound.
