阴道彩超及MRI诊断剖宫产术后子宫疤痕妊娠的临床价值

目的 探讨阴道彩超及MRI对剖宫产术后子宫疤痕妊娠的诊断价值.方法 回顾性分析经手术病理及临床证实的20例剖宫产术后子宫疤痕妊娠的临床资料,20例行阴道彩超,17例1周内行MRI检查.结果 20例中,阴道彩超诊断正确15例（75％）,误诊5例（25％）,阴道彩超诊断准确率为75％.阴道彩超分为两型：单纯妊娠囊型14例（70％）；混合回声包块型6例（30％）.MRI分为两型：单纯妊娠囊型：9例（约52.9％）；混杂团块型：8例（约47.1％）,17例MR检查均正确诊断.结论 剖宫产术后子宫疤痕妊娠的主要影像学表现为子宫疤痕处的囊性、囊实性结节或肿块.阴道彩超及MRI均可作出准确诊断,MRI在诊断子宫疤痕妊娠方面优于阴道彩超,可作为子宫疤痕妊娠的重要补充.

Transvaginal color doppler ultrasonography and magnetic resonance imaging for identifying cesarean scar pregnancy

Objective To evaluate the diagnostic value of transvaginal color doppler ultrasonography （TVCD） and magnetic resonance imaging （MRI） for identifying cesarean scar pregnancy （CSP）.Methods Clinical profiles of 20 patients with pathologically and clinically confirmed diagnosis of CSP who underwent TVCD followed by MRI in 17 cases at week 1 were retrospectively analyzed.Results Of 20 cases,15 （75%） and 5 （25%） were correctly and incorrectly diagnosed by TVCD,corresponding to a diagnostic accuracy of 75%,which was lower than that of MRI （100%）.Images result could be classified into gestational sac n=14 （70%） vs n=9 （52.9%）] and mixed mass type n=6 （30%） vs n=8 （47.1%）] based on TVCD and MRI,respectively.Conclusion The main image findings of CSP comprises cystic,solid and cystic nodules or masses,which can be properly identified by TVCD and MRI,of which the latter is superior and can be regarded as a crucial surrogate for assessment of CSP.
