摘要
目的探究体素内不相干运动成像定量参数联合超声评分法对产前前置胎盘伴胎盘植入的诊断价值。方法选取江苏省南通市妇幼保健院2017年3月至2021年9月收治的84例产前前置胎盘患者作为研究对象,所有受试者于孕35~38周时接受产前超声检查及MRI检查,分析患者产前体素内不相干运动成像定量参数及超声评分,另以患者产后病理或手术观察结果为金标准,根据患者是否合并胎盘植入将其分为植入组和非植入组。比较两组体素内不相干运动成像定量参数及超声评分、妊娠结局,以受试者操作特征曲线评价体素内不相干运动成像定量参数及超声评分诊断产前前置胎盘伴胎盘植入的诊断效能。结果84例前置胎盘患者中伴有胎盘植入31例(36.47%)。植入组产后出血、出生后1 min Apgar评分≤7分占比高于非植入组(P<0.05)。植入组超声评分高于非植入组,灌注分数(f值)低于非植入组(P<0.05)。f值及超声评分单一及联合诊断产前前置胎盘伴胎盘植入的诊断灵敏度分别为77.42%、80.65%、87.09%,特异度分别为71.70%、71.70%、75.47%。结论体素内不相干运动成像定量参数及超声评分对产前前置胎盘伴胎盘植入均具有较高的临床诊断效能。
Objective To explore the diagnostic value of quantitative parameters of intravoxel incoherent motion imaging combined with ultrasound scoring method for antenatal placenta previa with placenta accreta.Methods A total of 84 patients with antenatal placenta previa admitted to Nantong Maternity and Child Health Hospital of Jiangsu Province from March 2017 to September 2021 were selected as the research subjects.All subjects received antenatal ultrasound and MRI at 35-38 weeks of gestation.The quantitative parameters of intravoxel incoherent motion imaging and ultrasound score were analyzed,the results of postpartum pathology or surgery were taken as the gold standard,and the patients were divided into implantation group and non-implantation group according to whether they had placenta accreta.The quantitative parameters of intravoxel incoherent motion imaging and ultrasound scores,and pregnancy outcomes between the two groups were compared,receiver operating characteristic curve was used to evaluate the diagnostic efficacy of quantitative parameters of intravoxel incoherent motion imaging within voxel and ultrasound scores in the diagnosis of prenatal placenta previa with placenta accreta.Results Among the 84 patients with placenta previa,31 patients(36.47%)had placenta accreta.The proportions of postpartum hemorrhage and Apgar score≤7 at one minute after birth in implantation group were higher than those in non-implantation group(P<0.05).The ultrasound score of implantation group was higher than that of non-implantation group,and hepatic arerial fracture(f value)was lower than that of non-implantation group(P<0.05).The diagnostic sensitivity of single and combined f value and ultrasound score in the diagnosis of prenatal placenta previa with placental implantation were 77.42%,80.65%,and 87.09% respectively,the specificity were 71.70%,71.70%,and 75.47% respectively.Conclusion Quantitative parameters of intravoxel incoherent motion imaging and ultrasound scores have high clinical diagnostic efficacy for antenatal placenta previa with placenta accreta.
