产前MRI检查在凶险型前置胎盘合并胎盘植入诊断中的应用价值研究

Application Value of Prenatal MRI in the Diagnosis of Dangerous Placenta Previa with Placenta Accreta

目的临床诊断伴胎盘植入的凶险型前置胎盘患者时,应用产前MRI检查方案的效果及价值讨论。方法选取2020年9月—2021年9月兴义市人民医院疑似伴胎盘植入的75例凶险型前置胎盘患者为研究对象,均采取产前MRI检查和超声检查,以手术结果作为金标准,对比MRI检查与超声检查的敏感度、特异度、准确度。结果手术结果显示:伴胎盘植入患者45例、单纯凶险型前置胎盘患者30例;MRI检查的敏感度(93.33%)、特异度(90.00%)及准确度(92.00%)高于超声检查,差异有统计学意义(χ^(2)=19.200、5.400、24.200,P<0.05)。结论针对凶险型前置胎盘患者,在产前采取MRI检查,可以准确判断患者有无并发胎盘植入,其诊断效能较高,具有临床上应用价值。

Objective To evaluate the effect and value of prenatal MRI in the clinical diagnosis of dangerous placenta previa with placenta accreta.Methods 75 patients with dangerous placenta previa suspected with placenta implantation from September 2020 to September 2021 were selected as the research objects.Prenatal MRI and ultrasonography were used,and surgical results were taken as the gold standard to compare the sensitivity,specificity and accuracy of MRI and ultrasound.Results The results of the operation showed that 45 patients with placenta implantation and 30 patients with simple dangerous placenta previa;the sensitivity(93.33%),specificity(90.00%)and accuracy(92.00%)of MRI were higher than that of ultrasound,the difference was statistically significant(χ^(2)=19.200,5.400,24.200,P<0.05).Conclusion For patients with dangerous placenta previa,prenatal MRI examination can accurately determine whether the patients have concurrent placenta implantation,whose diagnostic efficiency is high and has clinical application value.
