摘　　要：目的探讨磁共振成像(MRI)与彩色多普勒超声(彩超)联合诊断凶险型前置胎盘伴胎盘植入的应用价值。方法62例疑似凶险型前置胎盘伴胎盘植入患者,均实施彩超和MRI联合彩超诊断,并和病理结果进行对比。观察彩超及MRI联合彩超诊断结果及声像图表现;比较彩超及MRI联合彩超的敏感度、特异度。结果手术诊断和(或)病理诊断结果为阳性47例,阴性15例,MRI联合彩超诊断结果中假阴性1例,占比1.6%;真阴性14例,占比22.6%;假阳性1例,占比1.6%;真阳性46例,占比74.2%。彩超诊断结果中假阴性6例,占比9.7%;真阴性9例,占比14.5%;假阳性6例,占比9.7%;真阳性41例,占比66.1%。MRI联合彩超的敏感度、特异度均高于彩超,差异具有统计学意义(P<0.05)。结论采用MRI与彩超联合诊断凶险型前置胎盘伴胎盘植入,可降低漏诊率,临床上应进一步推广应用。Objective To discuss the application value of magnetic resonance imaging(MRI)and color Doppler ultrasound in the diagnosis of dangerous placenta previa complicated with placenta accreta.Methods There were 62 cases of suspected pernicious placenta previa complicated with placenta accreta,and they were all diagnosed by color Doppler ultrasound and MRI combined with color Doppler ultrasound,and compared with the pathological results.The diagnostic results and sonographic performance of color Doppler ultrasound and MRI combined with color Doppler ultrasound were observed;the sensitivity and specificity of color Doppler ultrasound and MRI combined with color Doppler ultrasound were compared.Results The results of surgical diagnosis and/or pathological diagnosis were positive in 47 cases and negative in 15 cases.In the diagnosis of MRI combined with color Doppler ultrasound,there were 1 case of false negative,accounting for 1.6%,14 cases of true negative,accounting for 22.6%,1 case of false positive,accounting for 1.6%,46 cases of true positive,accounting for 74.2%.In the diagnosis of color Doppler ultrasound,there were 6 cases of false negative,accounting for 9.7%;9 cases of true negative,accounting for 14.5%;6 cases of false positive,accounting for 9.7%;41 cases of true positive,accounting for 66.1%.The sensitivity and specificity of MRI combined with color Doppler ultrasound were higher than those of the color Doppler ultrasound,and the difference was statistically significant(P<0.05).Conclusion Combination of MRI and color Doppler ultrasound can lower the missed diagnosis rate of dangerous placenta previa complicated with placenta accreta,and it can be further promoted and applied in clinic.
