目的:比较分析超声与磁共振成像(MRI)诊断凶险性前置胎盘的价值.方法:选取30例疑似凶险性前置胎盘患者为观察对象,均接受MRI检查与彩色多普勒超声检查,同时将术中检查结果当成金标准,分析比较超声、MRI诊断凶险性前置胎盘的价值.结果:全部30例患者中,术中检查结果显示26例阳性,4例阴性;将术中检查结果作为金标准,超声检查诊断凶险性前置胎盘患者的准确率为86.67%,灵敏度为88.46%,特异性为75.0%,阴性预测值为50.0%,阳性预测值为95.83%;MRI检查诊断凶险性前置胎盘患者的准确率为90.0%,灵敏度为92.31%,特异性为75.0%,阴性预测值为60.0%,阳性预测值为96.0%.在诊断准确率、灵敏度、特异性、阴性预测值及阳性预测值方面,超声检查与MRI检查比较差异无统计学意义(P>0.05).结论:在诊断凶险性前置胎盘时,超声检查与MRI检查的诊断效能相差不大,但是与MRI检查相比较,超声检查具有经济方便、可重复性好等特点,可以将其作为首选影像学诊断方式.
Comparative Analysis of Ultrasound and MRI in the Diagnosis of Dangerous Placenta Previa
Objective:To analyze and compare the value of ultrasound and MRI in the diagnosis of dangerous placenta previa.Methods:30 patients suspected of dangerous Placenta praevia were selected,all of whom received magnetic resonance imaging(MRI)and color Doppler ultrasound.At the same time,the results of intraoperative examination were taken as the gold standard,and the value of ultrasound and MRI in the diagnosis of dangerous placenta praevia was analyzed and compared.Results:Among all 30 patients,intraoperative examination results showed 26 cases were positive and 4 cases were negative;Using the results of intraoperative examination as the gold standard,the accuracy rate of ultrasound in the diagnosis of dangerous placenta praevia patients was 86.67%,the sensitivity was 88.46%,the specificity was 75.0%,the negative predictive value was 50.0%,and the positive predictive value was 95.83%;The accuracy of MRI in the diagnosis of dangerous placenta praevia was 90.0%,the sensitivity was 92.31%,the specificity was 75.0%,the negative predictive value was 60.0%,and the positive predictive value was 96.0%.There was no statistically significant difference between ultrasound and MRI in terms of diagnostic accuracy,sensitivity,specificity,negative predictive value,and positive predictive value(P>0.05).Conclusion:In the diagnosis of dangerous placenta previa,both ultrasound and MRI have the accuracy,specificity and sensitivity,and the imaging manifestations have the characteristics.In the actual clinical diagnosis,the best examination and diagnosis method can be selected according to the specific situation.
