摘要
目的探讨MRI对前置胎盘及合并胎盘植入的诊断价值。方法回顾分析手术及病理证实的15例前置胎盘患者的临床及MRI资料,包括1例前置胎盘合并胎盘植入及1例前置胎盘合并胎盘粘连,分析并总结其MRI诊断要点。结果完全性前置胎盘共6例,MRI对于完全性前置胎盘的诊断正确率为100.0%,但其中1例完全性前置胎盘合并胎盘粘连MRI术前漏诊,诊断符合率83.3%;部分性前置胎盘共3例,正确诊断2例,诊断符合率66.7%;边缘性前置胎盘共6例,诊断符合率为100.0%。而超声检查除1例完全性前置胎盘合并胎盘粘连漏诊外,其余病例均符合。结论 MRI对前置胎盘具有较高的诊断价值,多方位多角度观察有助于前置胎盘的明确分型。
Objective To investigate the value of MRI in diagnosis of placenta previa and its combination of placenta accrete. Materials and Methods Retrospective analysis the clinical data and MRI features of 15 Cases of placenta previa,whichconfirmed by operation and pathology,including 1 case of placentaaccreta,and 1 case with adherent placenta,analyze and summarize the diagnostic poinst of MRI imaging. Results There are 6 cases of complete placenta previa,thediagnosisof MRI was correct,1 case with adherent placenta were not diagnosed by MRI pre- operation,accordance rate was 83. 3%; 3 cases of partial placenta previa,MR diagnosed 2 cases,thediagnoseaccordance rate was 66. 7%; 6 cases of marginal placenta previa,thediagnose accordance rate was 100. 0%. US was not diagnose 1 case with adherent placenta,the rest of cases were diagnosed correctly. Conclusions MRI has a high diagnostic value of placenta previa,multi direction and multi angle observation make classification clearly.
