产前彩超与MRI诊断植入型凶险性前置胎盘的应用价值

Application value of prenatal color ultrasound and MRI diagnosis of implanted dangerous placenta previa

目的:探究产前彩超与MRI诊断植入型凶险性前置胎盘的诊断价值。方法:选取2020年1月~2021年6月广西壮族自治区玉林市第一人民医院收治的70例植入型凶险性前置胎盘患者为研究对象,根据诊断方式的不同进行分组,各35例,一组采用产前彩超诊断,另一组采用MRI诊断。两组诊断效果比较。结果:MRI组诊断子宫后壁胎盘植入的灵敏度、特异度高于产前彩超组,差异有统计学意义(P<0.05)。两组诊断胎盘前壁植入灵敏度、特异度、漏诊率、误诊率、诊断符合率差异无统计学意义(P>0.05)。结论:产前彩超与MRI诊断植入型凶险性前置胎盘均具有良好效果,彩超可作为首选,MRI可作为补充、进一步确诊检查手段。

Objective To explore the diagnostic value of prenatal color Doppler ultrasound and MRI in the diagnosis of pernicious placenta previa.Method From January 2020 to June 2021,70 patients with implanted dangerous placenta previa were admitted as the study subjects,according to different diagnostic methods,they were divided into groups,35 case in each group,one group was diagnosed with prenatal ultrasound,and the other group was diagnosed with MRI.Comparison of diagnostic effects between two groups.Results The sensitivity and specificity of the MRI group in diagnosing placental implantation in the posterior wall of the uterus were higher than those of the prenatal ultrasound group(P<0.05).There was no statistically significant difference in the sensitivity,specificity,missed diagnosis rate,misdiagnosis rate,and diagnostic accuracy between the two groups in diagnosing placental anterior wall implantation(P>0.05).Conclusion Prenatal color Doppler ultrasound and MRI have good results in the diagnosis of implantable dangerous placenta previa,color Doppler ultrasound can be used as the first choice,MRI can be used as a supplementary and further diagnostic means.
