摘　　要：研究分析腹部超声联合动态对比增强磁共振成像(DCE-MRI)在卵巢瘤样病变中的诊断灵敏性,以临床疑似卵巢瘤样病变患者为研究对象,所有患者术前均行腹部超声联合DCE-MRI检查,以术后病理结果为“金标准”,探究腹部超声联合DCE-MRI的阳性与阴性检出结果,对比腹部超声联合DCE-MRI的诊断效能(特异度、敏感度),同时比较腹部超声联合DCE-MRI检查的阻力指数(RI),使用配套软件自动计算容量转移常数(Ktrans)、速率常数(Kep)及血管外细胞外间隙容积比(Ve),作受试者操作特征(ROC)曲线分析模型诊断价值。结果发现,腹部超声联合DCE-MRI诊断的敏感度(96.77%)、特异度(98.55%)均高于单一腹部超声及DCE-MRI诊断结果(P<0.05);卵巢瘤样病变组RI指数高于卵巢肿瘤组,Ktrans、Kep、Ve水平低于卵巢肿瘤组(P<0.05);绘制ROC曲线预测模型最佳临界值为0.088,提示腹部超声联合DCE-MRI在卵巢瘤样病变中的诊断综合价值高。Studying the diagnostic sensitivity of abdominal ultrasound combined with dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI)in ovarian tumor-like lesions.In patients with clinically suspected ovarian tumor-like lesions.All patients underwent abdominal ultrasound DOS combined with DCE-MRI,with the postoperative pathological results as the“gold standard”.To explore the positive and negative findings of abdominal ultrasound combined with DCE-MRI.Compare the diagnostic efficacy of abdominal ultrasound combined with DCE-MRI(specificity,sensitivity).Also compare the resistance index(RI)of abdominal ultrasound combined with DCE-MRI examination.Automatic calculation of volume transfer constant(Ktrans),rate constant(Kep)and the vascular extracellular space volume ratio(Ve)using matching software.Receiver operator characteristic(ROC)curve analysis model diagnostic value.The results found that the sensitivity of abdominal ultrasound combined with DCE-MRI(96.77%)and specificity(98.55%)were higher than those of single abdominal ultrasound and DCE-MRI(P<0.05).The RI index of ovarian tumor group was higher than that of ovarian tumor group,and Ktrans,Kep and Ve levels were lower than that of ovarian tumor group(P<0.05).The optimal cut-off value of drawing ROC curve prediction model was 0.088,suggesting that the diagnostic value of abdominal ultrasound combined with DCE-MRI in ovarian tumor lesions was high.
