MRI技术在前置胎盘合并胎盘植入中的诊断应用体会

目的：探讨MRI在前置胎盘合并胎盘植入诊断的临床效果。方法回顾性分析2014年8月-2015年2月在我院经手术证实为前置胎盘50例患者的MRI资料，分析其影像学特点。结果采用MRI技术检查的50例患者中，明确诊断为前置胎盘患者为45例，其中4例为边缘性前置胎盘，12例为部分性前置胎盘，29例为完全性前置胎盘，诊断准确性90.00%，前置胎盘患者中，诊断合并胎盘植入患者19例，准确性为79.17%。结论 MRI技术对前置胎胎盘及胎盘植入诊断率高，能明确具体部位及胎盘植入情况，值得在临床推广应用。

The Application of MRI for Diagnosis of Placenta Praevia Combined with Placenta Accrete

Objective To investigate the application of MRI for diagnosis of placenta praevia combined with placenta accrete. Methods Totally 50 cases of placenta praevia combined with placenta accrete admitted to our hospital from August 2014 to February 2015 who was diagnosed by MRI were retrospectively analyzed.Results Based on MRI examination, 45 cases of placenta praevia was conifrmed. There were 4 cases, 12 cases and 29 cases of marginal placenta previa, partial placenta previa and complete placenta previa respectively. The MRI based diagnosis currency is 90%. There were 19 cases of placenta praevia combined with placenta accrete among all placenta accrete cases which suggested a diagnosis accuracy of 79.17%.Conclusion MRI technology demonstrated a high efficiency for placenta praevia combined with placenta accrete and could be a value toll for diagnosis.
