经腹超声与MRI对瘢痕妊娠的诊断价值

目的比较经腹超声与磁共振成像(MRI)对瘢痕妊娠的诊断价值。方法选取我院收治的60例拟诊瘢痕妊娠患者,均行经腹超声与MRI检查,以病理结果为金标准,比较经腹超声与MRI检查准确性、特异度与灵敏度。结果病理结果瘢痕妊娠阳性51例,阴性9例;经腹超声诊断瘢痕妊娠灵敏度80.39%(41/51),特异度66.67%(6/9),准确性78.33%(47/60),Kappa值0.36;MRI检查瘢痕妊娠灵敏度94.12%(48/51),特异度77.78%(7/9),准确性91.67%(55/60),Kappa值0.69;MRI检查瘢痕妊娠准确性明显高于经腹超声(P<0.05),两种检查方式特异度与灵敏度比较无显著差异(P>0.05)。结论相较于经腹超声,MRI检查瘢痕妊娠具有更高准确性,能为患者早期治疗方案合理选择提供更可靠信息指导。

Diagnostic Value of Transabdominal Ultrasound and MRI for Scar Pregnancy

Objective To compare the diagnostic value of transabdominal ultrasound and magnetic resonance imaging(MRI)for scar pregnancy.Methods 60 patients with suspected scar pregnancy admitted to the hospital were enrolled.All patients underwent transabdominal ultrasound and MRI.The accuracy,specificity and sensitivity of transabdominal ultrasound and MRI were compared according to thegold standardof pathological results.Results The pathological results were as follows:there were 51 cases with positive scar pregnancy,and 9 cases with negative.The sensitivity,specificity,accuracy and Kappa value of transabdominal ultrasound for diagnosis of scar pregnancy were 80.39%(41/51),66.67%(6/9),78.33%(47/60)and 0.36,respectively.The above 4 indexes of MRI were 94.12%(48/51),77.78%(7/9),91.67%(55/60)and 0.69,respectively.The accuracy of MRI was significantly higher than that of transabdominal ultrasound for diagnosis of scar pregnancy(P<0.05).There was no significant difference in specificity or sensitivity between the two examination methods(P>0.05).Conclusion Compared with transabdominal ultrasound,the accuracy of MRI is relatively higher for diagnosis of scar pregnancy,which can provide more reliable information guidance for rational selection of early treatment options.
