目的 探讨MRI诊断胎儿唇腭裂的征象及其优缺点.方法 对12例超声怀疑胎儿唇腭裂的孕妇进行胎儿MR检查,并将超声、MRI及随访结果进行对照.结果 12例孕妇,检出胎儿12例,随访结果显示1例为不完全型唇裂、11例为完全唇裂并合并腭裂.B超和MRI诊断唇裂的结果与随访一致.胎儿唇裂的MRI表现为胎儿唇部软组织连续性不完全或完全中断,内充填羊水,T2WI呈高信号.腭裂的MRI表现为胎儿腭部组织信号不连续、局部被长T_2高信号中断,口腔与鼻腔直接相通.MRI漏诊腭裂1例,正确诊断腭裂10例,正确排除腭裂1例,诊断正确率为91.7%(11/12),敏感度为90.9%(10/11),特异度为100%(1/1);B超诊断腭裂5例,正确排除腭裂1例,漏诊6例,诊断正确率为50.0%(6/12),敏感度为45.5%(5/11),特异度为100%(1/1).结论 MRI对于腭裂的诊断较B超有一定优势,在超声或其他检查怀疑胎儿有腭裂时,有必要进一步进行MR检查.
目的 探討MRI診斷胎兒脣腭裂的徵象及其優缺點.方法 對12例超聲懷疑胎兒脣腭裂的孕婦進行胎兒MR檢查,併將超聲、MRI及隨訪結果進行對照.結果 12例孕婦,檢齣胎兒12例,隨訪結果顯示1例為不完全型脣裂、11例為完全脣裂併閤併腭裂.B超和MRI診斷脣裂的結果與隨訪一緻.胎兒脣裂的MRI錶現為胎兒脣部軟組織連續性不完全或完全中斷,內充填羊水,T2WI呈高信號.腭裂的MRI錶現為胎兒腭部組織信號不連續、跼部被長T_2高信號中斷,口腔與鼻腔直接相通.MRI漏診腭裂1例,正確診斷腭裂10例,正確排除腭裂1例,診斷正確率為91.7%(11/12),敏感度為90.9%(10/11),特異度為100%(1/1);B超診斷腭裂5例,正確排除腭裂1例,漏診6例,診斷正確率為50.0%(6/12),敏感度為45.5%(5/11),特異度為100%(1/1).結論 MRI對于腭裂的診斷較B超有一定優勢,在超聲或其他檢查懷疑胎兒有腭裂時,有必要進一步進行MR檢查.

Objective To investigate the MR findings of fetal cleft lip (CL) and evaluate the advantages and limitations of MRI in the diagnosis. Methods Twelve pregnant women suspicious of fetal CL/cleft palate(CP) on ultrasonography were enrolled in the study. The findings of ultrasonography, MRI and following-up were compared. Results MRI and ultrasonography detected 12 fetuses with CL/CP. The following-up results showed 1 case with incomplete cleft lip and the other 11 cases with complete cleft lips and cleft palates. MRI and unltrasonography were consistent with the follow-up in CL detection, showing completed or uncompleted soft tissue interruption of the fetal lips with amniotic fluid filling which is high signal on T_2WI. On MRI, CP showed discontinuous of the soft tissue which were interrupted by long T_2 signal and communicating with oral cavity and nasal cavity. MRI missed 1 case and excluded 1 case of CP. Ultrasonography predicted 5 case of CL, excluded 1 CP but missed 6 cases. The accuracy, sensitivity and specificity in detection CL/CP was 91.7% (11/12), 90.9% (10/11), 100% (1/1) for MRI and 50.0% (6/12),45.5% (5/11), 100% (1/1) for ultrasonography, respectively. Conclusion MR imaging had advantage over ultrasonography in detecting CP, MRI is an essential when CP is suspicious on ultrasonography.
